Register 8-3:
ADCIF: Slope A/D Converter Comparator Trip Interrupt Flag bit
1 = An A/D conversion completed (must be cleared in software)
0 = The A/D conversion is not complete
OVFIF: Slope A/D TMR Overflow Interrupt Flag bit
1 = Slope A/D TMR overflowed (must be cleared in software)
0 = Slope A/D TMR did not overflow
PSPIF: Parallel Slave Port Read/Write Interrupt Flag bit
1 = A read or a write operation has taken place (must be cleared in software)
0 = No read or write has occurred
EEIF: EE Write Complete Interrupt Flag bit
1 = The data EEPROM write operation is complete (must be cleared in software)
0 = The data EEPROM write operation is not complete
LCDIF: LCD Interrupt Flag bit
1 = LCD interrupt has occurred (must be cleared in software)
0 = LCD interrupt has not occurred
CMIF: Comparator Interrupt Flag bit
1 = Comparator input has changed (must be cleared in software)
0 = Comparator input has not changed
Legend
R = Readable bit
U = Unimplemented bit, read as ‘0’
Note 1: The bit position of the flag bits is device dependent. Please refer to the device data
sheet for bit placement.
