FIGURE 25-4:
25.2.1
The MSSPx module has five registers for SPI mode
operation. These are:
• MSSPx STATUS register (SSPxSTAT)
• MSSPx Control Register 1 (SSPxCON1)
• MSSPx Control Register 3 (SSPxCON3)
• MSSPx Data Buffer register (SSPxBUF)
• MSSPx Address register (SSPxADD)
• MSSPx Shift register (SSPxSR)
SSPxCON1 and SSPxSTAT are the control and STA-
TUS registers in SPI mode operation. The SSPxCON1
register is readable and writable. The lower 6 bits of
the SSPxSTAT are read-only. The upper two bits of the
SSPxSTAT are read/write.
In one SPI master mode, SSPxADD can be loaded
with a value used in the Baud Rate Generator. More
information on the Baud Rate Generator is available in
Section 25.7 “Baud Rate
SSPxSR is the shift register used for shifting data in
and out. SSPxBUF provides indirect access to the
SSPxSR register. SSPxBUF is the buffer register to
which data bytes are written, and from which data
bytes are read.
In receive operations, SSPxSR and SSPxBUF
together create a buffered receiver. When SSPxSR
receives a complete byte, it is transferred to SSPxBUF
and the SSPxIF interrupt is set.
During transmission, the SSPxBUF is not buffered. A
write to SSPxBUF will write to both SSPxBUF and
SSPxSR.
