When the I/O port is set as input, the pull-up/pull-down state can be programmed in 1-bit units. If set as the input state of an I/O port and a backup release enable state, the backup state can be released by changing input state in the clock stop and the wait modes. Pins P3-0 to P3-2 are used as input/output pins of a serial interface circuit. The serial interface circuit corresponds to 2-wired, 3-wired and UART types. Serial clock edge, serial clock input/output and clock frequency are selectable, facilitating the control of various LSIs and communication between controllers. When interruption of a serial interface circuit is permitted, interruption occurs and a program is jumped to the 3rd address after the serial interface operation is completed. The P3-3 pin is used as 8-bit pulse counter input PCTRin. Since it is possible to select either or both of the rising edge and falling edge of the input pin, as well as count-up or count-down, the pin can be used as an input to a tape count. Input instruction Release enables VDD VDD VDD RIN1 |
