Overview 1.5. Pin Function PIN NAME INPUT OUTPUT FUNCTION @RESET @STOP K0 ~ K3 R0 ~ R2 -. 4-bit I/O port. (Input mode is set only when each of them output `H`) -. Each pin has STOP mode release function Key-Strobe in input mode. (at T-key Scan) -. Output mode is set when each of them output `L`. Input or I/O -. When used as `output`, each pin can be set and (with Pull-up) Keep status reset independently. Before STOP -. When set as the input mode, input state of pin is (at M-key Scan) read. At output mode, if port is read, data register is read instead of the state of pin. P0 ~ P3 -. 4-bit I/O port. (Input mode is set only when each of them output `H`) -. Each pin has STOP mode release function in input mode. Key-Strobe -. Output mode is set when each of them outp […]
