Input or

Output

Input

Request to sendÑ

This signal functions as the UART RTS signal.

Input compare 2 A

ÑWhen so programmed, this signal connects to

an Input Capture Timer channel.

The signal is a GPIO when not programmed as one of the above

functions. After reset, the default state for this signal is GPI.

Alternate:

MUX_CTL driven high

RESET_IN

Input

Reset input

ÑThis signal is an active low Schmitt trigger input that

provides a reset signal to the internal circuitry. The input is valid if

it is asserted for at least three CKIL clock cycles.

Note:

When this signal is enabled, the primary RESET_IN signal

is disabled. (See Table 1-11 on page 1-17.)
