This read-only field is reserved and always has the value 0.
2
CPOWOI
Compute Operation Wake-up on Interrupt
0 No effect.
1 When set, the CPOREQ is cleared on any interrupt or exception vector fetch.
1
CPOACK
Compute Operation Acknowledge
0 Compute operation entry has not completed or compute operation exit has completed.
1 Compute operation entry has completed or compute operation exit has not completed.
0
CPOREQ
Compute Operation Request
This bit is auto-cleared by vector fetching if CPOWOI = 1.
0 Request is cleared.
1 Request Compute Operation.
33.3 Functional description
This section describes the functional description of MCM module.
33.3.1 Interrupts
The MCM generates two interrupt requests:
• Non-maskable interrupt
• Normal interrupt
33.3.1.1 Non-maskable interrupt
The MCM's NMI is generated if:
• ISCR[ETBN] is set, when
• The ETB counter is enabled, ETBCC[CNTEN] = 1
• The ETB count expires
• The response to counter expiration is an NMI, MCM_ETBCC[RSPT] = 10
