P0B (P0B3, P0B2, P0B1, P0B0) P0C (P0C1, P0C0) P0D (P0D3, P0D2) I/O mode selector flag VDD VDD RESET Output latch 1 0 Write instruction Read instruction Port register (1 bit) 10.2.2 Use of I/O ports The I/O port is set in the input or output mode by the I/O select registers P0B and P0C of the control register. P0D, P0C, and P0D are the bit I/O ports. Therefore, these ports can set in input or output mode in 1-bit units. To set output data or to read input data, data is written to the corresponding port register, or an instruction that reads the data is executed. 10.2.3 describes the configuration of the I/O select register of each port. 10.2.4 describes how to use an I/O port as an input port. 10.2.5 describes how to use an I/O port as an output port. |
