OSCFIF — SSP2IF BCL2IF BCL1IF HLVDIF TMR3IF TMR3GIF

bit 7 bit 0

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 OSCFIF: Oscillator Fail Interrupt Flag bit

1 = Device oscillator failed, clock input has changed to INTOSC (must be cleared in software)

0 = Device clock is operating

bit 6 Unimplemented: Read as ‘0’

bit 5 SSP2IF: Master Synchronous Serial Port Interrupt Flag bit

1 = The transmission/reception has been completed (must be cleared in software)

0 = Waiting to transmit/receive

bit 4 BCL2IF: Bus Collision Interrupt Flag bit

1 = A bus collision occurred (must be cleared in software)

0 = No bus collision occurred

bit 3 BCL1IF: Bus Collision Interrupt Flag bit

1 = A bus collision occurred (must be cleared in software)

0 = No bus collision occurred

bit 2 HLVDIF: High/Low-Voltage Detect Interrupt Flag bit

1 = A low-voltage condition occurred (must be cleared in software)

0 = The device voltage is above the regulator’s low-voltage trip point

bit 1 TMR3IF: TMR3 Overflow Interrupt Flag bit

1 = TMR3 register overflowed (must be cleared in software)

0 = TMR3 register did not overflow

bit 0 TMR3GIF: TMR3 Gate Interrupt Flag bit

1 = Timer gate interrupt occurred (must be cleared in software)

0 = No timer gate interrupt occurred
