Summary
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.
Alternate Mode (TxCON[1] == 1) for timer 0 and 1 has some functional issues.
When the extension byte (mod field) is set to ―11,‖ some instructions will cause the
CPU to hang.
When the chip is put in SFNM mode for INT0 or INT1, the LVL bit is automatically
set for those interrupts.
Timer 2 will stop or not start counting.
Write does not occur when counter is actively counting.
Program Counter can become corrupted if an interrupt occurs.
Bound instruction uses bad data when index addresses are on odd boundary in
memory.
Alternate Mode (TxCON[1] == 1) for timer 0 and 1 has some functional issues.
