CHAPTER 24 EXAMPLES OF MB90F481B/MB90F482B/MB90F488B/MB90F489B SERIAL PROGRAMMING

Oscillation clock frequency and serial clock input frequency

The serial clock frequencies that can be used for input to the MB90F481B, MB90F482B,

MB90F488B, and MB90F489B can be calculated from the following formulas.

Use the flash microcontroller programmer settings to set the serial clock input frequency for the

required oscillation clock frequency.

Serial clock frequency to be input = 0.125 x oscillation clock frequency

Table 24.1-2 shows a serial clock frequency that can be input.
