12-bit Free-Running Timer
The 12-bit timer operates with a 1-s tick, provides two interrupts (128 s 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 can be read directly by the firmware. Reading the lower eight
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 can be read, even when the two
reads are separated in time.
Bit [7:0]: Timer lower eight bits
Bit [3:0]: Timer higher nibble
Bit [7:4]: Reserved.
