Operation
8-bit Free-running Timer (Timer 6)
The generation cycle of the timer interrupt should be set in advance by selecting the clock source and setting the
compare register (TM6OC). When the binary counter (TM6BC) reaches the setting value of the compare register,
an interrupt request is generated at the next count clock and the binary counter is cleared to restart counting up
from 0x00.
Table:10.3.1 shows selectable clock sources.
Table:10.3.1 Clock Source at Timer Operation (Timer 6)
..
When SCLK is used as the clock source, the timer counts at "falling edge" of the count clock.
When other clock is used, it counts "rising edge" of the count clock.
