The Input Buffer Status bit of the PSPCON register
(PSPCON<7>) may be inadvertently cleared,
even when the PORTD input buffer has not been
read. This will occur only when the following two
conditions occur simultaneously:
•
•
Work around
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.
1. When developing or modifying code, keep
2. If accessing a part of Bank 15 is required and
3. If pointing the BSR to Bank 15 is unavoidable,
High priority interrupts may become improperly
enabled, while low priority interrupts become
improperly disabled at the same time. This may
occur when low priority interrupts are in an
enabled state and the following conditions occur
simultaneously:
•
•
The four Least Significant bits of the
BSR register are equal to 0Fh
(BSR<3:0> = 1111), and
Any instruction that contains 83h in its
8 Least Significant bits (i.e., register file
addresses, literal data, address offsets,
etc.) is executed.

instructions contains 83h in the 8 Least Signif-
icant bits while the BSR points to Bank 15
(BSR = 0Fh).
High priority interrupts are being changed
from an enabled to a disabled state; and
One or more low priority interrupts occur.
Assign 12-bit addresses to all variables.
This allows the assembler to know when
Access Banking can be used.
Do not set the BSR to point to Bank 15
(BSR = 0Fh).
Allow the assembler to manipulate the
Access bit present in most instructions.
Accessing the SFRs in Bank 15 will be
done through the Access Bank. Con-
