1) The ECMOCIF is physically implemented in register ECMDIAG (Table 3.30) and mapped to IRQSTAT.
Table 3.10 IRQSTAT Register Bits Description
Bit Description
WDTIF: WDT interrupt flag.
7
1 = Watchdog timer time-out occurred during STANDBY Mode.
0 = Watchdog timer interrupt did not occur.
Note: In order to clear WDTIF, the MCU must clear the WDT by toggling the WDTCLR bit (see Table 3.4).
OVTIF: Over-temperature interrupt flag.
6 ^{1 = Over-temperature event occurred.}
0 = Over-temperature event did not occur.
Note: In order to clear OVTIF, the MCU should clear the OVTF flag in register RSTSTAT (Table 3.1).
SEIF: Supply error interrupt flag.
1 = The system supply voltage is out of range. There was an overvoltage or under-voltage event, and as a result,
one of the flags OVIF or UVIF is set.
5
0 = A supply error interrupt has not occurred. The supply voltage is in range.
Note: The SEIF cannot be directly cleared. In order to clear SEIF, the MCU should clear the CPVEIF, OVIF, and
UVIF flags in the RSTSTAT register.
ADCIF: ADC global interrupt flag.
1 = ADC interrupt occurred. The ADC conversion is ready or the comparator threshold has been reached.
4 0 = ADC interrupt did not occur.
Note: The ADCIF interrupt flag cannot be directly cleared. ADCIF is cleared by clearing the correlated ADCRDYIF or
ADCCMPIF flags in the ADCSTAT register (Table 3.39).
HBOCIF: Half-bridge driver over-current global interrupt flag.
1 = An over-current event was detected in one or more of the half-bridge drivers. To determine the specific over-
3
current source, the MCU should read the HBxOCIF bits in the HBDSTAT register (Table 3.15).
0 = A half-bridge driver over-current event was not detected.
Note: The HBOCIF interrupt flag cannot be directly cleared. In order to clear HBOCIF, the MCU should clear the
HBxOCIF flags in the HBDSTAT register.
