Section 7 I/O Ports
7.2
Output Buffer Control
This section describes the output priority of each pin.
The name of each peripheral module pin is followed by "_OE". This (for example: TIOCA4_OE)
indicates whether the output of the corresponding function is valid (1) or if another setting is
specified (0). Table 7.4 lists each port output signal's valid setting. For details on the
corresponding output signals, see the register description of each peripheral module.
