Detail
TxOUT will continuously toggle at 1/2 CLKOUT regardless of count register values.
The maxcount compare will not work. The live count will compare against TxCMPA and
TxCMPB in alternate cycles. This could cause a compare (and the associated interrupt,
or switch the intended compare, or stop counting altogether) to occur early or not at all.
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.
Alternate Mode (TxCON[1] == 1) for timer 0 and 1 has some functional issues.
Illegal serial port modes do not match OEM part.
Non-maskable interrupt (NMI) can be pre-empted by maskable interrupt.
Ready signal may not be recognized in bus cycles with zero wait states.
None.
