Note:

For input with interrupt possibility “eix” defines the associated external interrupt vector which can be as-

signed to one of the I/O pins using the EISR register. Each interrupt can be either weak pull-up or floating

defined through option register OR.

Caution: During normal operation this

pin must be pulled- up, internally or ex-

ternally (external pull-up of 10k manda-

tory in noisy environment). This is to

avoid entering ICC mode unexpectedly

during a reset. In the application, even if

the pin is configured as output, any re-

set will put it back in input pull-up.
