| CBD8210::CBD8210 | ( | unsigned int | b | ) |
Default constructor.
Default constructor. This is called when declarations of the form e.g.:
Definition at line 307 of file CBD8210.cpp.
References m_pBTB, m_pBZ, m_pCAR, m_pCsr, m_pGL, m_pITF, and CCamacModule::MakePointer().
| CBD8210::CBD8210 | ( | const CBD8210 & | rhs | ) |
Copy constructor.
Copy construction. This is invoked when e.g. an object is passed by value to a function. The copy constructor makes a clone of the rhs object.
Definition at line 333 of file CBD8210.cpp.
Assignment.
Assignment operation. This member function supports assignment of an object of this class to an object of the same class.

| volatile unsigned long* CBD8210::getGL | ( | ) | [inline] |
| bool CBD8210::Xtest | ( | ) | const |
Returns true if the last operation on this branch returned an X response. The X response indicates that the module has 'responded' to the function code.
Definition at line 389 of file CBD8210.cpp.
| bool CBD8210::Qtest | ( | ) | const |
Returns true if the last operation on this branch returned a valid Q. The meaning of the Q bit depends on the module and the function being performned. Q's are often used to send the result of a test function back (e.g. test for lam), indicate the end of a block transfer and other module specific functions.

Referenced by CCrateController::isDemandEnabled(), CCrateController::isDemanding(), and CCrateController::isInhibited().
| bool CBD8210::TimedOut | ( | ) | const |
Returns true if the last operation on the branch timed out (The TO bit is set in the CSR). This usually indicates that a crate which was offline was addressed.
Definition at line 421 of file CBD8210.cpp.
| bool CBD8210::BranchDemand | ( | ) | const |
Returns true if a global demand is pending on the branch.
Definition at line 433 of file CBD8210.cpp.
| void CBD8210::MNoX | ( | bool | fset = true |
) |
Sets the state of the MNox bit in the status register. When this bit is clear, operations which don't provoke an X response result in a VME bus error. In general, this bit should be set disabling this bus error.
| fSet | - true if the bit should be set. |
Definition at line 449 of file CBD8210.cpp.
| void CBD8210::MTo | ( | bool | fset = true |
) |
Controls the state of the MTO bit in the control status register. When this bit is clear, Branch timeouts (accesses to nonexistent cratss) result in bus errors on the VME bus. This bit should normally be set as there's no way to catch these bus errors as an inline trap.
| fset | - true to set the bit. |
Definition at line 474 of file CBD8210.cpp.
| void CBD8210::MLAM | ( | bool | fset = true |
) |
Controls the state of the MLAM bit in the CSR. When this bit is clear, a LAM produces an VME interrupt at IPL3. This bit should normally be set as there is no time efficient way to catch these interrupts at process level.
| fset | - When true the MLAM bit will be set. |
Definition at line 500 of file CBD8210.cpp.
| void CBD8210::MIT2 | ( | bool | fset = true |
) |
When clear, a NIM true on the IT2 will create a VME interrupt at IPL2. This bit should normally be set as there is no time efficient way to catch VME interrupts at process level.
| fset | - If true MIT2 is set. |
Definition at line 524 of file CBD8210.cpp.
| void CBD8210::MIT4 | ( | bool | fset = true |
) |
When clear, a NIM true on IT4 will produce a VME bus interrupt at IPL4. Since there's no good time efficient way to catch these interrupts at process level, this bit should be set.
| fset | - If true, the MIT4 bit will be set. |
Definition at line 548 of file CBD8210.cpp.
| bool CBD8210::IT2 | ( | ) | const |
Returns true if the IT2 bit is set in the CSR. This bit is set to indicate that the IT2 input has received a falling edge. To reset the edge, you must write the IFR with the IT2 bit.
Definition at line 571 of file CBD8210.cpp.
| bool CBD8210::IT4 | ( | ) | const |
True if the IT4 bit is set in the CSR. This bit indicates that a falling NIM edge was presented to the IT4 input of the module. To clear this latched bit the IFR must be written with the IT4 bit.
Definition at line 587 of file CBD8210.cpp.
| unsigned short CBD8210::ReadCsr | ( | ) | const |
Returns the current value of the CSR.

| void CBD8210::WriteCsr | ( | unsigned short | nMask | ) |
Writes the CSR with the mask of bits supplied:
| nMask | - The mask of bits to write. |
Definition at line 611 of file CBD8210.cpp.
References m_pCsr.
| void CBD8210::WriteIFR | ( | unsigned short | nMask | ) |
Writes the IFR (interrupt flag register) with the specified mask. The bits in this register reset the IT2 and IT4 bits in the CSR.
| nMask | - Mask to write in the IFR. |

| unsigned short CBD8210::ReadBTB | ( | ) | const |
Returns the value of the BTB register. In practice, the bits in this register specify which crates are powered up and online. The map of these bits is:
7 6 5 4 3 2 1 0 +-----------------------------------------------------------------+ | ... Cr7 | Cr6 | Cr5 | Cr4 | Cr3 | Cr2 | Cr1 | 0| +------------------------------------------------------------------+

| unsigned long CBD8210::ReadGl | ( | ) | const |
Returns the current value of the branch graded demand. This may have nothing to do with crate LAMs. To get a crate LAM, you should read the individual crate GL registers.
