SPI Mode for PIC16C72/73/73A/74/74A
D/A: Data/Address bit (I
1 = Indicates that the last byte received or transmitted was data
0 = Indicates that the last byte received or transmitted was address
P: Stop bit (I
1 = Indicates that a stop bit has been detected last (this bit is '0' on RESET)
0 = Stop bit was not detected last
S: Start bit (I
1 = Indicates that a start bit has been detected last (this bit is '0' on RESET)
0 = Start bit was not detected last
R/W: Read/Write bit information (I
This bit holds the R/W bit information following the last address match. This bit is valid from the address
match to the next start bit, stop bit, or ACK bit.
1 = Read
0 = Write
UA: Update Address (10-bit I
1 = Indicates that the user needs to update the address in the SSPADD register
0 = Address does not need to be updated
BF: Buffer Full Status bit
Receive (SPI and I
1 = Receive complete, SSPBUF is full
0 = Receive not complete, SSPBUF is empty
Transmit (I
1 = Transmit in progress, SSPBUF is full
0 = Transmit complete, SSPBUF is empty
