6.2 Clock Generator
Clock generator configuration
The clock generator provides the clock signals to the CPU and peripheral hardware and its configuration
is shown in Figure 6-1.
The operation of the clock generator is set with the processor clock control register (PCC).
The instruction execution time can be changed.
0.95, 1.91, 3.81, 15.3

0.67, 1.33, 2.67, 10.7
s (system clock operating at 6.0 MHz)
