When the device is configured for either EC or RC
oscillator modes, with the Power-up Timer
enabled, bit TO of the RCON register (RCON<3>)
may default to ‘0’, even though no WDT time-out
has occurred.
The TO bit functions normally in all other configu-
rations.

2. Use the latest silicon revision when it becomes
The BF Status bit (SSPSTAT<0>) may be reset by
certain literal operations, even if the buffer has not
been read. This will occur when both of the
following conditions are met:

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

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.

Register (BSR) are 0Fh, and
A literal operation with an argument of 0C9h

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.

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:
