The FUNC bits in the IOCON registers can be set to GPIO (FUNC = 000) or to a
peripheral function. If the pins are GPIO pins, the GPIOnDIR registers determine whether
the pin is configured as an input or output (see
the pin direction is controlled automatically depending on the pin’s functionality. The
GPIOnDIR registers have no effect for peripheral functions.
The MODE bits in the IOCON register allow the selection of on-chip pull-up or pull-down
resistors for each pin or select the repeater mode.
The possible on-chip resistor configurations are pull-up enabled, pull-down enabled, or no
pull-up/pull-down. The default value is pull-up enabled.
The repeater mode enables the pull-up resistor if the pin is at a logic HIGH and enables
the pull-down resistor if the pin is at a logic LOW. This causes the pin to retain its last
known state if it is configured as an input and is not driven externally. The state retention is
not applicable to the Deep power-down mode. Repeater mode may typically be used to
prevent a pin from floating (and potentially using significant power if it floats to an
indeterminate state) if it is temporarily not driven.
The input buffer for digital functions can be configured with hysteresis or as plain buffer
through the IOCON registers (see the EM773 data sheet for details).
