Notes:
1. This pin cannot be configured as external interrupt in ROM devices.
2. OSC1 and OSC2 are not multiplexed in ROM devices and Port C is not present.
3. PCOR not implemented but p-transistor always active in output mode (refer to Figure 29 on page 45)

Caution: During normal operation
this pin must be pulled- up, internal-
ly or externally (external pull-up of
10k mandatory in noisy environ-
ment). This is to avoid entering ICC
mode unexpectedly during a reset.
In the application, even if the pin is
configured as output, any reset puts
it back in input pull-up
