SMP
SMP: Sample bit
SPI Master mode:
1 = Input data sampled at end of data output time
0 = Input data sampled at middle of data output time
SPI Slave mode:
SMP must be cleared when SPI is used in Slave mode.
CKE: SPI Clock Edge Select bit
SPI mode, CKP = 0:
1 = Data transmitted on rising edge of SCK
0 = Data transmitted on falling edge of SCK
SPI mode, CKP = 1:
1 = Data transmitted on falling edge of SCK
0 = Data transmitted on rising edge of SCK
I
This bit must be maintained clear.
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
This bit is cleared when the SSP module is disabled or when the Start bit is detected last; 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 (I
This bit is cleared when the SSP module is disabled or when the Stop bit is detected last; 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 Information bit (I
This bit holds the R/W bit information following the last address match. This bit is only valid from the
address match to the next Start bit, Stop bit or ACK bit.
1 = Read
0 = Write
UA: Update Address bit (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
