SPI Mode for PIC16CR72
This section contains register definitions and opera-
tional characteristics of the SPI module on the
PIC16CR72 device only.
Additional information on SPI operation may be found
in the PICmicro Mid-Range MCU Reference Manual,
DS33023.

R = Readable bit
W =Writable bit
U = Unimplemented bit,

bit 7:
SMP:
SPI data input sample phase
SPI Master Operation
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
CKP = 0
1 = Data transmitted on rising edge of SCK
0 = Data transmitted on falling edge of SCK
CKP = 1
1 = Data transmitted on falling edge of SCK
0 = Data transmitted on rising edge of SCK
D/A
: Data/Address bit (I
2
C 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 (I
2
C mode only. 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
2
C mode only. 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 bit information (I
2
C mode only)
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 (10-bit I
2
C mode only)
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
2
C modes)
1 = Receive complete, SSPBUF is full
0 = Receive not complete, SSPBUF is empty
Transmit (I
2
C mode only)
1 = Transmit in progress, SSPBUF is full
0 = Transmit complete, SSPBUF is empty
