Note 1:
When the MSSP is configured for SPI Master
mode, the SDO pin cannot be disabled by setting
the TRISC<5> bit. The SDO pin always outputs
the content of SSPBUF regardless of the state of
the TRIS bit.
In Slave mode with slave select enabled,
SSPM3:SSPM0 = 0010 (SSPCON1<3:0>), the
SDO pin can be disabled by placing a logic high
level on the SS pin (RA5).

After an I
register may be written for up to 10 T
additional writes are blocked. The data transfer
may be corrupted if SSPBUF is written to during
this time.
The WCOL bit is set anytime an SSPBUF write
occurs during a transfer.

Avoid writing SSPBUF until the data transfer is
complete, indicated by the setting of the SSPIF bit
(PIR1<3>).
Verify the WCOL bit (SSPCON1<7>) is clear after
writing SSPBUF to ensure any potential transfer in
progress is not corrupted.
