16. Clock
The clock generator module controls the operation of the internal clock circuits that serve as the operating clock
for the CPU and peripheral devices. This internal clock is referred to as the machine clock, and one cycle is referred
to as a machine cycle. Also, the clock signals from the base oscillator are called the oscillator clock, and those from
the PLL oscillator are called the PLL clock.
