Refer to the ATD block description chapter for information on the ATDDIEN0 and ATDDIEN1 registers.
During reset, port AD pins are configured as high-impedance analog inputs (digital input buffer is
disabled).
3.3.1.1
Read: Anytime. Write: Anytime.
If the data direction bit of the associated I/O pin (DDRADx) is set to 1 (output), a write to the
corresponding I/O Register bit sets the value to be driven to the Port AD pin. If the data direction bit of the
associated I/O pin (DDRADx) is set to 0 (input), a write to the corresponding I/O Register bit takes place
but has no effect on the Port AD pin.
If the associated data direction bit (DDRADx) is set to 1 (output), a read returns the value of the I/O register
bit.
If the associated data direction bit (DDRADx) is set to 0 (input) and the associated ATDDIEN0(1) bit is
set to 0 (digital input buffer is disabled), the associated I/O register bit (PTADx) reads “1”.
If the associated data direction bit (DDRADx) is set to 0 (input) and the associated ATDDIEN0(1) bit is
set to 1 (digital input buffer is enabled), a read returns the value of the pin.
