OE7-0 ... Output Enable for AUX7 - AUX0
0: Pin AUX7-0 is configured as output. The value of the corresponding bit in the ATX
register is driven on AUX7-0.
1: Pin AUX7-0 is configured as input. The value of the corresponding bit can be read from
the ARX register.
Note: In NT and LT modes the pins AUX0-2 are not available as I/O pins.
Data Sheet
This configuration is only valid if the corresponding output enable bit in AOE is
disabled.
If pins AUX7, AUX6 are to be used as interrupt input, OE7, OE6 must be set to 1.
If pins AUX7, AUX5 and AUX4 are not used as I/O pins (see ACFG2), the
corresponding OEx bit cannot be set, but delivers the mode dependent direction
(input/output) in that function upon a read access. If the secondary function is
disabled, the direction of the pin as I/O pin is valid again.
