PIC18CXX2
Register 7-5: Peripheral Interrupt Request (Flag) Registers (cont’d)
PIR2
bit 7-4
bit 3
Unimplemented: Read as ’0’
BCLIF: Bus Collision Interrupt Flag bit
1= A Bus Collision occurred
(must be cleared in software)
0= No Bus Collision occurred
bit 2
bit 1
bit 0
LVDIF: Low-Voltage Detect Interrupt Flag bit
1= A low voltage condition occurred
(must be cleared in software)
0= The device voltage is above the Low Voltage Detect trip point
TMR3IF: TMR3 Overflow Interrupt Flag bit
1= TMR3 register overflowed
(must be cleared in software)
0= TMR3 register did not overflow
CCP2IF: CCPx Interrupt Flag bit
Capture Mode
1= A TMR1 register capture occurred
(must be cleared in software)
0= No TMR1 register capture occurred
Compare Mode
1= A TMR1 register compare match occurred
(must be cleared in software)
0= No TMR1 register compare match occurred
PWM Mode
Unused in this mode
Legend:
R = Readable bit
W = Writable bit
U = Unimplemented bit, read as ‘0’
’0’ = Bit is cleared x = Bit is unknown
- n = Value at POR reset
’1’ = Bit is set
