The above connection example is when "UART, MPC and parity no mode" was used as the

"host CPU interface, and when CLKOUT output of the host CPU" was used as the clock for

MSM6636.

Depending on the control target, an optimum host CPU (number of ports, A/D converter yes

/ no) can be selected, and an optimum system can be constructed.
