The System Tick Timer is a 24-bit timer that counts down to zero and generates an
interrupt. The intent is to provide a fixed 10 millisecond time interval between interrupts.
The System Tick Timer is clocked from the CPU clock. In order to generate recurring
interrupts at a specific interval, the LOAD register must be initialized with the correct value
for the desired interval.
The block diagram of the System Tick Timer is shown below in the
