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 13.5 lists each port output signal's valid setting. For details on the

corresponding output signals, see the register description of each peripheral module. If the name

of each peripheral module pin is followed by A or B, the pin function can be modified by the port

function control register (PFCR). For details, see section 13.3, Port Function Controller.

For a pin whose initial value changes according to the activation mode, "initial value E" indicates

the initial value when the LSI is started up in external extended mode and "initial value S"

indicates the initial value when the LSI is started in single-chip mode.
