21.1.3
This LSI (ML610Q429 only) includes Port A (PA0 to PA5) which is an 6-bit input/output port.
This function is not included in the ML610Q428.
• Allows selection of high-impedance output, P-channel open drain output, N-channel open drain output, or CMOS
• Allows selection of high-impedance input, input with a pull-down resistor, or input with a pull-up resistor for each
• PA5 to PA0 is used as common port (COM23 to COM18) in ML610Q428.
Figure 21-1 shows the configuration of Port A.
