When configured for I
MSSP module may not receive the correct data, in
extremely rare cases. This occurs only if the Serial
Receive/Transmit Buffer Register (SSPBUF) is not
read after the SSPIF interrupt (PIR1<3>) has
occurred, but before the first rising clock edge of
the next byte being received.
Work around
The issue can be resolved in either of these ways:
• Prior to the I
• Each time the SSPIF is set, read the SSPBUF
