Legend:
R = Readable bit
-n = Value at POR
W = Writable bit
‘1’ = Bit is set
U = Unimplemented bit, read as ‘0’
‘0’ = Bit is cleared
x = Bit is unknown
bit 7
bit 6
bit 5
bit 4
bit 3-0
Unimplemented: Read as ‘0’
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
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
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
Unimplemented: Read as ‘0’
