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

Unimplemented: Read as ‘0’

bit 6

LCDIF: LCD Interrupt Flag bit (valid when Type-B waveform with Non-Static mode is selected)

= LCD data of all COMs is output (must be cleared in software)

= LCD data of all COMs is not yet output

bit 5

RC2IF: AUSART Receive Interrupt Flag bit

= The AUSART receive buffer, RCREG2, is full (cleared when RCREG2 is read)

= The AUSART receive buffer is empty

bit 4

TX2IF: AUSART Transmit Interrupt Flag bit

= The AUSART transmit buffer, TXREG2, is empty (cleared when TXREG2 is written)

= The AUSART transmit buffer is full

bit 3

CTMUIF: CTMU Interrupt Flag bit

= CTMU interrupt occured (must be cleared in software)

= No CTMU interrupt occured

bit 2

CCP2IF: CCP2 Interrupt Flag bit
Capture mode:
1

= A TMR1/TMR3 register capture occurred (must be cleared in software)

= No TMR1/TMR3 register capture occurred

Compare mode:
1

= A TMR1/TMR3 register compare match occurred (must be cleared in software)

= No TMR1/TMR3 register compare match occurred

PWM mode:
Unused in this mode.
