18.1.3
This LSI includes Port 0 (P00 to P03) which is a 4-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 P00 and P01 pins can be used as the trigger input pins of the capture circuit and the P02 pin can be used as the
