Programmable Timer Registers
Timer 6 is a 8-bit programmable counter.
Programmable counter consists of compare register (TM6OC) and binary counter (TM6BC).
Binary counter is a 8-bit up counter. When the TM6CLRS flag of the timer 6 mode register (TM6MD) is
"0" and the interrupt cycle data is written to the compare register (TM6OC), the timer 6 binary counter
(TM6BC) is cleared to x'00'.
