Only for PLCC 68 pins :
OE3 Direction Control for IO3
0 : Pin IO3's output driver is disabled and input driver is enabled
1 : Pin IO3's output driver is enabled.
Note:
The ACLT2: INT1M bit should be set to “0”, INT1/IO3 pin can be as IO. Otherwise, It is configured as
interrupt input.
OE2 Direction Control for IO2
0 : Pin IO2's output driver is disabled and input driver is enabled
1 : Pin IO2's output driver is enabled.
Note:
The ACLT2: INT0M bit should be set to “0”, INT0/IO2 pin can be as IO. Otherwise, It is configured as
interrupt input.
OE1 Direction Control for IO1
0 : Pin IO1's output driver is disabled and input driver is enabled
1 : Pin IO1's output driver is enabled.
OE0 Direction Control for IO0
0 : Pin IO0's output driver is disabled and input driver is enabled
1 : Pin IO0's output driver is enabled.
