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 Unimplemented: Read as ‘0’
bit 6 LCDIF: LCD Interrupt Flag bit (valid when Type-B waveform with Non-Static mode is selected)
1 = LCD data of all COMs is output (must be cleared in software)
0 = LCD data of all COMs is not yet output
bit 5 RC2IF: AUSART Receive Interrupt Flag bit
1 = The AUSART receive buffer, RCREG2, is full (cleared when RCREG2 is read)
0 = The AUSART receive buffer is empty
bit 4 TX2IF: AUSART Transmit Interrupt Flag bit
1 = The AUSART transmit buffer, TXREG2, is empty (cleared when TXREG2 is written)
0 = The AUSART transmit buffer is full
bit 3-0 Unimplemented: Read as ‘0’
