The Buffer Full flag bit (BF) of the SSPSTAT regis-
ter (SSPSTAT<0>) may be inadvertently cleared,
even when the SSPBUF register has not been
read. This will occur only when the following two
conditions occur simultaneously:
• The four Least Significant bits of the BSR
• Any instruction that contains C9h in its 8 Least

Identified work arounds will involve setting the
contents of BSR<3:0> to some value other than
0Fh.
In addition to those proposed below, other solutions
may exist.

• Assign 12-bit addresses to all variables.
• Do not set the BSR to point to Bank 15

3. Module: MSSP (SPI, Slave Mode)
In its current implementation, the SS (Slave
Select) control signal generated by an external
master processor may not be successfully recog-
nized by the PIC
Slave Select mode (SSPM3:SSPM0 = 0100). In
particular, it has been observed that faster transi-
tions (those with shorter fall times) are more likely
to be missed than slower transitions.
Work around
Insert a series resistor between the source of the
SS signal and the corresponding SS input line of
the microcontroller. The value of the resistor is
dependent on both the application system’s
characteristics and process variations between
microcontrollers. Experimentation and thorough
testing is encouraged.
This is a recommended solution; others may exist.
