CHAPTER 29 EXAMPLE OF SERIAL PROGRAMMING CONNECTION
Oscillation Clock Frequency and Serial Clock Input Frequency
The permitted frequency for the input serial clock on the MB95170J is calculated from the following
formula. Accordingly, adjust the settings on the flash microcomputer programmer so that the serial clock
input frequency matches the oscillation clock frequency being used.
Permitted frequency for the input serial clock = 0.125 × Oscillation clock frequency
Example:
Oscillation clock
frequency
input to the microcomputer
at 4MHz
at 8MHz
at 10MHz

Note:
Although the AF200 flash microcomputer programmer is an old model, this can be handled using the
FF201 control module. The connection examples shown in the next chapter can also be used as
example connections for serial writing.
