TC0C COUNTING REGISTER  
TC0C is an 8-bit counter register for the timer (TC0). TC0C must be reset whenever the TC0ENB is set to “1” to start  
the timer. TC0C is incremented each time a clock pulse of the frequency determined by TC0RATE0 ~ TC0RATE2.  
When TC0C has incremented to “0FFH”, it counts to “00H” an overflow generated. Under TC0 interrupt service request  
(TC0IEN) enable condition, the TC0 interrupt request flag will be set to “1” and the system executes the interrupt  
service routine. The TC0C has no auto reload function. After TC0C overflow, the TC0C is continuing counting. Users  
need to reset TC0C value to get an accurate time.

The equation of TC0C initial value is as following.  
TC0C initial value = 256 - (TC0 interrupt interval time * input clock)  
Example: To set 10ms interval time for TC0 interrupt at 3.58MHz high-speed mode. TC0C value (74H) =  
256 - (10ms * fcpu/64)  
TC0C initial value = 256 - (TC0 interrupt interval time * input clock)  
= 256 - (10ms * 3.58 * 106 / 4 / 64)  
= 256 - (10-2 * 3.58 * 106 / 4 / 64)  
= 116  
= 74H
