12-bit Free-running Timer
The 12-bit timer 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 8 bits of the timer can be read
directly by the firmware. Reading the lower 8 bits latches the

upper 4 bits into a temporary register. When the firmware
reads the upper 4 bits of the timer, it is actually reading the
count stored in the temporary register. The effect of this logic
is to ensure a stable 12-bit timer value can be read, even when
the two reads are separated in time.

writing to the processor status and control register, the run bit
should always be written as a “1.”
