1. Transmission
In SCLK output mode 8-bit data and a synchronous clock are output on the
TXD0 and SCLK0 pins respectively each time the CPU writes the data to the
transmission buffer. When all data is outputted, INTES0 will be set to
generate the INTTX0 interrupt.
Figure 3.9.19 Transmission Operation in I/O Interface Mode (SCLK0 output mode)
In SCLK input mode, 8-bit data is output from the TXD0 pin when the SCLK0
input becomes active after the data has been written to the transmission buffer by
the CPU.
When all data is outputted, INTES0 will be set to generate INTTX0
interrupt.
