3.8.5 G5. APE CPU Event Register Test
Command: nictest g5
Function: In this test the APE CPU writes to the APE event registers to verify that each
event state can generate a corresponding interrupt.
Default: Enabled
3.8.6 G6. APE CPU Mutex Register Test
Command: nictest g6
Function: Each of the registers in the APE Mutex Register block is tested from the APE
CPU. This test verifies that each bit set in the Mutex Request register can acquire a
corresponding grant bit in its paired Mutex Grant register. After each grant bit is set it is
written with back to verify the grant bit can be cleared.
Default: Enabled

Command: nictest g7
Function: This test each of the APE internal timer registers using the APE CPU. The test
verifies that the timers are functioning and within acceptable tolerances.
