Generic Description of Overriding Signals for Alternate Functions
Full Name
Description
If this signal is set, the pull-up enable is controlled by the PUOV
Pull-up Override
signal. If this signal is cleared, the pull-up is enabled when
Enable
{DDxn, PORTxn, PUD} = 0b010.
If PUOE is set, the pull-up is enabled/disabled when PUOV is
Pull-up Override
set/cleared, regardless of the setting of the DDxn, PORTxn,
Value
and PUD Register bits.
If this signal is set, the Output Driver Enable is controlled by the
Data Direction
DDOV signal. If this signal is cleared, the Output driver is
Override Enable
enabled by the DDxn Register bit.
If DDOE is set, the Output Driver is enabled/disabled when
Data Direction
DDOV is set/cleared, regardless of the setting of the DDxn
Override Value
Register bit.
If this signal is set and the Output Driver is enabled, the port
Port Value
value is controlled by the PVOV signal. If PVOE is cleared, and
Override Enable
the Output Driver is enabled, the port Value is controlled by the
PORTxn Register bit.
Port Value
If PVOE is set, the port value is set to PVOV, regardless of the
Override Value
setting of the PORTxn Register bit.
Port Toggle
If PTOE is set, the PORTxn Register bit is inverted.
Override Enable
Digital Input
If this bit is set, the Digital Input Enable is controlled by the
Enable Override
DIEOV signal. If this signal is cleared, the Digital Input Enable
Enable
is determined by MCU state (Normal mode, sleep mode).
Digital Input
If DIEOE is set, the Digital Input is enabled/disabled when
Enable Override
DIEOV is set/cleared, regardless of the MCU state (Normal
Value
mode, sleep mode).
This is the Digital Input to alternate functions. In the figure, the
signal is connected to the output of the Schmitt Trigger but
Digital Input
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
Analog
signal is connected directly to the pad, and can be used bi-
Input/Output
directionally.
