OC1 Flag (0xD5: Bit 0)
Indicates whether cycle-by-cycle Overcurrent 1 condition is detected or not.
When this flag is altered, OC1 has occurred and the phase location can be obtained by reading Fault Status Register-10 (0xD9).
0XD5 BIT0
DESCRIPTION
0
OK: OC1 is not detected.
1
OC1 is detected at PWMx.
OC2 Fault Flag (0xD5: Bit 1)
Indicates whether cycle-by-cycle Overcurrent 2 (OC2) condition is detected or not.
When this flag is altered, OC2 has occurred and the phase location can be obtained by reading Fault Status Register-11 (0xDA).
0XD5 BIT1
DESCRIPTION
0
OK: OC2 is not detected.
1
OC2 is detected at PWMx.
