Vers. 1.0 by E. Bendels


This Application Note gives a short example on how to calculate timer settings for configuring the
PWM-Timer so that the UART clock of the MB89630 can be provided by the timer.

Background:

The UART block of the MB89630 series controller allows to select its required clock signal from 4
different sources.
The 1st source is a dedicated baud-rate generator belongin
