15.2
The MSSP module has three associated registers.
These include a status register and two control registers.
REGISTER 15-1:
DS30475A-page 136
Control Registers
bit 7
bit 6
bit 5
bit 4
bit 3
bit 2
SSPSTAT REGISTER
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
In I
1= Slew rate control disabled for standard speed mode (100 kHz and 1 MHz)
0= Slew rate control enabled for high speed mode (400 kHz)
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
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 only valid from
the address match to the next START bit, STOP bit, or not ACK bit.
In I
1 = Read
0 = Write
In I
1 = Transmit is in progress
0 = Transmit is not in progress

Register 15-1 shows the MSSP Status Register
(SSPSTAT), Register 15-2 shows the MSSP Control
Register 1 (SSPCON1), and Register 15-3 shows the
MSSP Control Register 2 (SSPCON2).
