Workaround:
Errata No. 2
Problem:
CPU to hang.
Description:
used by compilers), the following instructions will cause the CPU to hang when the extension
byte (mod field) is set to ―11‖:
Workaround:
Errata No. 3
Problem:
set for those interrupts.
Workaround:
8D (LEA)
8F (POP memory)
C6 (MOV immediate8 to memory/register)
C7 (MOV immediate16 to memory/register)
FE (PUSH memory)
FF (PUSH memory)
The TxOUT pin may start in the wrong state if the user writes to TxCON register
Bit [12].
When in retrigger mode, Timer 1 will not function correctly. Input pulses on T0IN will
cause counter to begin counting.
