11.1.1 Overview
The clock generator module plays a main role in making a stable operating clock, SCLK. There’s only
one clock source in MC96FR364B, which is the output of main oscillator, XINCLK, connected to the
XIN and XOUT pins. The main clock input XINCLK is divided by 2, 4 or 8, and one of the divided
clocks is used as internal operating clock, SCLK, according to the DIV[1:0] bits in SCCR register. By
default, frequency of SCLK is same as that of XINCLK, ie, divided by 1.
