12-Bit Free-Running Timer
The 12-bit timer operates with a 1 μs tick, provides two interrupts (128 μs and 1.024 ms) and allows the firmware to directly time events
that are up to 4 ms in duration. The lower eight bits of the timer is read directly by the firmware. Reading the lower 8 bits latches the
upper four bits into a temporary register. When the firmware reads the upper four bits of the timer, it is actually reading the count stored
in the temporary register. The effect of this is to ensure a stable 12-bit timer value is read, even when the two reads are separated in
time.
