This is repeated for each DAW instruction
The DAW instruction may improperly clear the
Carry bit (STATUS<0>) when executed.
Work around
Test the Carry bit state before executing the DAW
instruction. If the Carry bit is set, increment the
next higher byte to be added, using an instruction
such as INCFSZ (this instruction does not affect
any Status flags and will not overflow a BCD
nibble). After the DAW instruction has been
executed, process the Carry bit normally (see
Example 1).
Date Codes that pertain to this issue:
All engineering and production devices.
When performing writes on the external memory
interface, a short glitch is present on the LB and
UB lines. The length of the glitch is proportional to
F
temperature. The glitch occurs well before the
WRH line is asserted and no adverse affect on the
operation of the external memory interface has
been observed.
Work around

The Buffer Full (BF) flag bit 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

All 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.
