PIC18F87J90 FAMILY
18.3.1
Each MSSP module has four registers for SPI mode
operation. These are:
• MSSP Control Register 1 (SSPCON1)
• MSSP Status Register (SSPSTAT)
• Serial Receive/Transmit Buffer Register (SSPBUF)
• MSSP Shift Register (SSPSR) – Not directly
SSPCON1 and SSPSTAT are the control and status
registers in SPI mode operation. The SSPCON1
register is readable and writable. The lower 6 bits of
the SSPSTAT are read-only. The upper two bits of the
SSPSTAT are read/write.

SMP
Polarity of the clock state is set by the CKP bit (SSPCON1<4>).
REGISTERS
SMP: Sample bit
SPI Master mode:
1 = Input data sampled at the end of data output time
0 = Input data sampled at the middle of data output time
SPI Slave mode:
SMP must be cleared when SPI is used in Slave mode.
CKE: SPI Clock Select bit
1 = Transmit occurs on transition from active to Idle clock state
0 = Transmit occurs on transition from Idle to active clock state
D/A: Data/Address bit

BF: Buffer Full Status bit (Receive mode only)
1 = Receive complete; SSPBUF is full
0 = Receive not complete; SSPBUF is empty

SSPSR is the shift register used for shifting data in or
out. SSPBUF is the buffer register to which data bytes
are written to or read from.
In receive operations, SSPSR and SSPBUF together,
create a double-buffered receiver. When SSPSR
receives a complete byte, it is transferred to SSPBUF
and the SSPIF interrupt is set.
During
double-buffered. A write to SSPBUF will write to both,
SSPBUF and SSPSR.
