7.7 Register information
7.7.1 COUNT - rolling counter register (address 00h)
The count register is a read-only register that provides the current value of a free-running
8-bit counter derived from the primary oscillator. A 10-bit prescaler divides the primary
oscillator frequency by 1000. Thus, the value in the register increases by one count every
100 μs and the counter rolls over every 25.6 ms.
