Description
If this signal is set, the pull-up enable is controlled by the
PUOV signal. If this signal is cleared, the pull-up is
enabled when {DDxn, PORTxn, PUD} = 0b010.
If PUOE is set, the pull-up is enabled/disabled when
PUOV is set/cleared, regardless of the setting of the
DDxn, PORTxn, and PUD Register bits.
If this signal is set, the Output Driver Enable is controlled
by the DDOV signal. If this signal is cleared, the Output
driver is enabled by the DDxn Register bit.
If DDOE is set, the Output Driver is enabled/disabled
when DDOV is set/cleared, regardless of the setting of the
DDxn Register bit.
If this signal is set and the Output Driver is enabled, the
port value is controlled by the PVOV signal. If PVOE is
cleared, and the Output Driver is enabled, the port Value is
controlled by the PORTxn Register bit.
If PVOE is set, the port value is set to PVOV, regardless of
the setting of the PORTxn Register bit.
If this bit is set, the Digital Input Enable is controlled by the
DIEOV signal. If this signal is cleared, the Digital Input
Enable is determined by MCU state (Normal Mode, Sleep
Modes).
If DIEOE is set, the Digital Input is enabled/disabled when
DIEOV is set/cleared, regardless of the MCU state
(Normal Mode, Sleep Modes).
This is the Digital Input to alternate functions. In the figure,
the signal is connected to the output of the schmitt trigger
but before the synchronizer. Unless the Digital Input is
used as a clock source, the module with the alternate
function will use its own synchronizer.
This is the Analog Input/output to/from alternate functions.
The signal is connected directly to the pad, and can be
used bi-directionally.
