The PIC16F83 (Rev. A) parts you have received conform
functionally to the Device Data Sheet (DS30430 C ),
except for the anomalies described below.
All the problems listed here will be addressed in future
revisions of the PIC16F83 silicon.

Module: CPU (STATUS bit)
The operation of the power-down (PD) bit in the STA-
TUS register may not function correctly for tempera-
tures below - 20 ˚C.
Work Around
None
Module: Data EEPROM
Do not perform a modify (set or clear a bit) of the
EECON1 register one instruction cycle after an
EEPROM read. This will corrupt the EEDATA regis-
ter.
Example:
BSF
BCF
Work Around
Use either of the following two code segment in place
of the above example.
BSF
NOP
BCF
or
BCF

Module: Timer0
The TMR0 register may increment when the WDT
postscaler is switched to the Timer0 prescaler. If
TMR0 = FFh, this will cause TMR0 to overflow (set-
ting T0IF).
Work Around
Follow the following sequence:
Read the 8-bit TMR0 register into the W register
Clear the TMR0 register
Assign WDT postscaler to Timer0
Write W register to TMR0
