MB90560/565 Series
The control circuit shown in the figure is required when the P00, P01, SIN1, SOT1, and SCK0 pins are used on
the user system. Use the /TICS signal from the flash microcontroller writer to disconnect the user circuit during
serial on-board programming.

Control circuit
Use the formula below to calculate the serial clock frequency able to be input to the MB90F562/F562B/F568.
Set up the flash microcontroller writer to use a serial clock input frequency that is permitted for the oscillation
clock frequency you are using.
Permitted input serial clock frequency = 0.125 × oscillation clock frequency
