AIODx
0
Data bits that are used to control the level of the Address Bus configured as I/O output pins, and to monitor
the level of the Address Bus configured as I/O input pins. AIOD15 and AIOD14 are only available in BGA
package.
If AIODIRn = 0, then:
AIODx = 0
Corresponding I/O pin is read as a low.
AIODx = 1
Corresponding I/O pin is read as a high.
If AIODIRn = 1, then:
AIODx = 0
AIODx = 1
Set corresponding I/O pin to low.
Set corresponding I/O pin to high.
