PIR2 Register

The PIR2 register contains the Peripheral Interrupt

Flag bits, as shown in Register 15-5.

Note 1: Interrupt flag bits are set when an

interrupt condition occurs, regardless of

the state of its corresponding enable bit

or the Global Enable bit (GIE) in the

INTCON register. The user’s software

should ensure the appropriate interrupt

flag bits are clear prior to enabling an

interrupt.

Legend:

R = Readable bit

W = Writable bit

U = Unimplemented bit, read as ‘0’

-n = Value at POR

‘1’ = Bit is set

‘0’ = Bit is cleared

x = Bit is unknown

bit 7

CDSIF: DESAT Detect comparator module interrupt flag bit

1 = An interrupt is pending

0 = An interrupt is not pending

bit 6

ADIF: ADC Interrupt Flag bit

1 = ADC conversion complete

0 = ADC conversion has not completed or has not been started

bit 5

Unimplemented: Read as ‘0’

bit 4

OTIF: Overtemperature Interrupt Flag bit

1 = Overtemperature event has occurred

0 = Overtemperature event has not occurred

bit 3

OVIF: Overvoltage Interrupt Flag bit

With OVINTP bit set:

1 = A VOUT Not Overvoltage-to-Overvoltage edge has been detected

0 = A VOUT Not Overvoltage-to-Overvoltage edge has not been detected

With OVINTN bit set:

1 = A VOUT Overvoltage-to-Not Overvoltage edge has been detected

0 = A VOUT Overvoltage-to-Not Overvoltage edge has not been detected

bit 2

DRUVIF: Gate Drive Undervoltage Lockout Interrupt Flag bit

1 = Gate Drive Undervoltage Lockout has occurred

0 = Gate Drive Undervoltage Lockout has not occurred

bit 1

OVLOIF: VIN Overvoltage Lockout Interrupt Flag bit

With OVLOINTP bit set:

1 = A VIN Not Overvoltage-to-VIN Overvoltage edge has been detected

0 = A VIN Not Overvoltage-to-VIN Overvoltage edge has not been detected

With OVLOINTN bit set:

1 = A VIN Overvoltage-to-VIN Not Overvoltage edge has been detected

0 = A VIN Overvoltage-to-VIN Not Overvoltage edge has not been detected

bit 0

UVLOIF: VIN Undervoltage Lockout Interrupt Flag bit

With UVLOINTP bit set:

1 = A VIN Not Undervoltage-to-VIN Undervoltage edge has been detected

0 = A VIN Not Undervoltage-to-VIN Undervoltage edge has not been detected

With UVLOINTN bit set:

1 = A VIN Undervoltage-to-VIN Not Undervoltage edge has been detected

0 = A VIN Undervoltage-to-VIN Not Undervoltage edge has not been detected
