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
