16.1 Overview
16.1.1
16.1.2
This LSI includes Port 0 (P00 to P07) which is a 8-bit input port.
• All bits support a maskable interrupt function.
• Allows selection of interrupt disabled mode, falling-edge interrupt mode, rising-edge interrupt mode, or both-edge
• Allows selection of with/without interrupt sampling for each bit.(Sampling frequency: T16KHZ)
• Allows selection of high-impedance input mode, input mode with a pull-down resistor, or input mode with a pull-up
• The P02 pin can be used as the RXD0 input pin of UART0, or the external clock input pin for PWM2.
• P03 to P00 is used as common port (COM17 to COM14) in ML610Q428.
