The above connection example is when “UART, MPC and 'parity no' mode” is used as the “host CPU interface,
and when “CLKOUT output of the host CPU” is used as the clock for the MSM6636.
An optimum system can be constructed by selecting an optimum host CPU (number of ports, A/D converter
yes/no) for the control target and combining it with the MSM6636.
*1 Insert a capacitor between the power supply and GND as a countermeasure for noise.
It is recommended that a small-capacitance bypass capacitor and a large-capacitance filter capacitor be
connected in parallel. Typical capacitors are as follows:
0.01 to 0.22 F: Ceramic capacitor
10 to 100 F:
Tantalum capacitor
