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
SMP: SPI Data Input Sample Phase 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
bit 6
CKE: SPI Clock Edge Select bit
SPI mode, CKP = 0:
1 = Data stable on rising edge of SCK
0 = Data stable on falling edge of SCK
SPI mode, CKP = 1:
1 = Data stable on falling edge of SCK
0 = Data stable on rising edge of SCK
bit 5
D/A: Data/Address bit
Used in I²C mode only.
bit 4
P: Stop bit
Used in I²C mode only.
bit 3
S: Start bit
Used in I²C mode only.
bit 2
R/W: Read/Write Information bit
Used in I²C mode only.
bit 1
UA: Update Address bit
Used in I²C mode only.
bit 0
BF: Buffer Full Status bit
1 = Receive complete, SSPBUF is full
0 = Receive not complete, SSPBUF is empty
