7. Module: MSSP (SPI Slave)
© 2008 Microchip Technology Inc.
If configured in SPI Slave mode, the MSSP may not
successfully recognize data packets generated by an
external master processor. This applies to all SPI
Slave modes (CKE/CKP = 1 or 0), whether or not
slave select is enabled (SSPM3:SSPM0 = 010x).
Work around
Insert a series resistor between the SPI master
Serial Data Out (SDO) and the corresponding SPI
slave Serial Data In (SDI) input line of the
microcontroller. The required value for the resistor
varies with the application system’s characteristics
and
microcontrollers.
Experimentation
encouraged.

When operated in I
baud rate may be somewhat slower than predicted
by the following formula:
Work around
If the target application is sensitive to the baud rate
and requires more precision, the SSPADD value
can be adjusted to compensate.
If this work around is going to be used, it is recom-
mended that the firmware first check the Revision
ID by reading the DEVID1 value at address
3FFFFEh. Silicon revisions B6 and B7 will match
