5.2.1 Channel Registers
This register is used to specify which events should result in an interrupt asserted to the VMEbus.
Interrupt Mask Register
Channel Offset Read/Write | 7 | 6 | 5 | 4 | 3 | 2 | 1 | 0 |
$0F | MF_Ua2 | MF_Ua1 | MF_DI | MF_IND | MCAR | MBOR | MDI | MIND |
- MF_Ua2
- When this bit is set, and the corresponding F_Ua2 bit in the Direct Input Register is set, an interrupt request to the Bus Interrupter Module (BIM) will be active.
- MF_Ua1
- When this bit is set, and the corresponding F_Ua1 bit in the Direct Input Register is set, an interrupt request to the Bus Interrupter Module (BIM) will be active.
- MF_DI
- When this bit is set, and the corresponding F_DI bit in the Direct Input Register is set, an interrupt request to the Bus Interrupter Module (BIM) will be active.
- MF_IND
- When this bit is set, and the corresponding F_IND bit in the Direct Input Register is set, an interrupt request to the Bus Interrupter Module (BIM) will be active.
- MCAR
- When this bit is set, and the corresponding CAR bit in the Index Status Register is set, then an interrupt request to the Bus Interrupter Module (BIM) will be active.
- MBOR
- When this bit is set, and the corresponding MOR bit in the Index Status Register is set, then an interrupt request to the Bus Interrupter Module (BIM) will be active.
- MDI
- When this bit is set, a difference between the DI bit and the CDI bit will cause an interrupt request to the Bus Interrupter Module (BIM).
- MIND
- When this bit is set, a difference between the IND bit and the CIND bit will cause an interrupt request to the Bus Interrupter Module (BIM).
After a SYSRESET these bits are cleared.
