Input/Output Ports
7.14 Port D (PD0 to PD7)
The port D is a general-purpose, 7-bit input/output port. For this port, inputs and outputs can be specified in
units of bits by using the control register PDCR and the function registers PDFC1 and PDFC2. A reset allows all
bits of the output latch PD to be set to "1," all bits of PDCR, PDFC1 and PDFC2 to be cleared to "0," and the
port D to be put in input mode.
Input is disabled right after reset. To enable input, set the corresponding bit of PDIE to “1”.
Besides the input port function, the port D performs other functions: PD0 outputs HSIO data, PD1 inputs HSIO
data, PD2 inputs and outputs HSIO HCLK or inputs HCTS, PD3, PD4 and PD5 output a 16-bit timer, and PD6
inputs the key-on wake-up, PD6 and PD7 input A/D triggers into the A/D converter.
