22. EEPROM page buffer always written when NVM DATA0 is written
23. Pending full asynchronous pin change interrupts will not wake the device
24. Pin configuration does not affect Analog Comparator Output
25. Low level interrupt triggered when pin input is disabled
26. JTAG enable does not override Analog Comparator B output
27. NMI Flag for Crystal Oscillator Failure automatically cleared
If the EEPROM is memory mapped, writing to NVM DATA0 will corrupt data in the EEPROM
page buffer.
Problem fix/Workaround
Before writing to NVM DATA0, for example when doing software CRC or flash page buffer
write, check if EEPROM page buffer active loading flag (EELOAD) is set. Do not write NVM
DATA0 when EELOAD is set.
Any full asynchronous pin-change Interrupt from pin 2, on any port, that is pending when the
sleep instruction is executed, will be ignored until the device is woken from another source
or the source triggers again. This applies when entering all sleep modes where the System
Clock is stopped.
Problem fix/Workaround
None.
The Output/Pull and inverted pin configuration does not affect the Analog Comparator out-
put function.
Problem fix/Workaround
None for Output/Pull configuration.
For inverted I/O, configure the Analog Comparator to give an inverted result (i.e. connect
positive input to the negative AC input and vice versa), or use and external inverter to
change polarity of Analog Comparator output.
If a pin input is disabled, but pin is configured to trigger on low level, interrupt request will be
sent.
Problem fix/Workaround
Ensure that Interrupt mask for the disabled pin is cleared.
When JTAG is enabled this will not override the Analog Comparator B (ACB) output,
AC0OUT on pin 7 if this is enabled.
Problem fix/Workaround
Use Analog Comparator output for ACA when JTAG is used, or use the PDI as debug
interface.
NMI flag for Crystal Oscillator Failure (XOSCFDIF) will be automatically cleared when exe-
cuting the NMI interrupt handler.
Problem fix/Workaround
This device revision has only one NMI interrupt source, so checking the interrupt source in
software is not required.
