This LSI (ML610Q431 only) includes Port A (PA0 to PA7) which is an 8-bit input/output port.
This function is not included in the ML610Q422.
• Allows selection of high-impedance output, P-channel open drain output, N-channel open drain output, or CMOS output
• Allows selection of high-impedance input, input with a pull-down resistor, or input with a pull-up resistor for each bit
Figure 22-1 shows the configuration of Port A.
