R = Readable bit

bit0 W = Writable bit

U = Unimplemented bit,

read as ‘0’

- n =Value at POR reset

Unimplemented: Read as '0'

D/A: Data/Address bit (I2C mode only)

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 (I2C mode only. This bit is cleared when the SSP module is disabled, SSPEN is cleared)

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 (I2C mode only. This bit is cleared when the SSP module is disabled, SSPEN is cleared)

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 (I2C mode only)

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 I2C mode only)

1 = Indicates that the user needs to update the address in the SSPADD register

0 = Address does not need to be updated

bit 0:

BF: Buffer Full Status bit

Receive (SPI and I2C modes)

1 = Receive complete, SSPBUF is full

0 = Receive not complete, SSPBUF is empty

Transmit (I2C mode only)

1 = Transmit in progress, SSPBUF is full

0 = Transmit complete, SSPBUF is empty
