Port Direction Registers
When pins are used as ports, the register bits control the corresponding pins as follows.
0: Input mode
1: Output mode
Bits are set to “0” by a reset.
Note: No register bits are provided for bit 6 to 7 of port 5.
No register bit is provided for bit 7 of port 7.
No register bit is provided for bit 7 of port 8.
No register bit is provided for bit 0 of port A.
No register bits are provided for bits 6 to 7 of port 9.
Port 6 does not have a DDR.
Port 1 is only available when the external data bus is in 8-bit mode. Access is prohibited in 16-bit mode.
Ports 2 and 3 are only available in multiplex mode. Access is prohibited in non-multiplex mode.
Analog Input Enable Register
Controls each pin of port 6 as follows.
0: Port input mode
1: Analog input mode
Bits are set to “1” by a reset.
Note: Inputting an intermediate level signal in port input mode causes an input leak current to flow. Therefore, set
to analog input mode when applying an analog input.
