Figure 10: Timer block diagram
The timer clock is generated by a prescale unit. The timer clock may be one of:
The CKTIMER
The CKTIMER divided by 16, generated by 4 bits of prescale
the CKTIMER divided by 256, generated by a total of 8 bits of prescale
Figure 11: Pre-scaler block diagram
Using the recommended 2.208Mhz clock, the minimum interval between two timer interrupt is 452nsec (corre-
sponding to the 2.208Mhz period) while the maximum interval between two timer interrupt is around 6sec.
