The 10 Hz, 100 Hz and 200 Hz timer is output to 10 Hz, 100 Hz and 200 Hz bits respectively with frequency pulses of
100 ms, 10 ms and 5 ms respectively. The 10 Hz and 100 Hz timers have a duty cycle of 50%. The 200 Hz timer is output at
a duty cycle of 60% with a high level of 3 ms and a low level of 2 ms. Counters at 1 kHz or below will be reset whenever
the reset port's timer bit is set to "1".
100 Hz or 200 Hz timer can be selected for the interrupt. When timer interrupt is enabled, interrupt is generated on the
rising of this pulse. If interrupt is received, a program will branch to 0003H address.
