Register | Description |
---|---|
PORTx.PINCONFIG | PINnCTRL (ISC, PULLUPEN and INVEN) setting to prepare simultaneous configuration of multiple PINnCTRL registers |
PORTx.PINCTRLUPD | Writing a ‘1 ’
to bit n in the PINCTRLUPD register will copy the
PINCONFIG register content to the PINnCTRL
register |
PORTx.PINCTRLSET(1) | Writing a ‘1 ’
to bit n in the PINCTRLSET register will set the
individual bits in the PINnCTRL register,
according to the bits set to ‘1 ’
in the PINCONFIG register |
PORTx.PINCTRLCLR(2) | Writing a ‘1 ’ to bit n in
the PINCTRLCLR register will clear the individual
bits in the PINnCTRL register, according to the
bits set to ‘1 ’ in the PINCONFIG
register |
The following code snippet demonstrates how to configure multiple PINnCTRL registers, of multiple ports.
PORTA.PINCONFIG = PORT_ISC_INPUT_DISABLE_gc; /* The setting to load to the PINnCTRL registers */ PORTA.PINCTRLUPD = 0xff; PORTB.PINCTRLUPD = 0xff; PORTC.PINCTRLUPD = 0xff; PORTD.PINCTRLUPD = 0xff; PORTE.PINCTRLUPD = 0xff;
