Work around
When all of the following conditions are met:
• The module is configured as a SPI slave
• CKP = 1
• CKE = 1
• Multiple bytes are sent with the SS line
The SSPIF flag will only be set on reception of the
first byte and the following bytes will not be
correctly received.
• Toggle the SS line between bytes

module as a SPI slave with SS pin disabled.
Then restore the SSPM bits to the configuration
for SPI slave with SS pin enabled. The module
is then ready for reception of the following byte.
