Timer2
Timer2 is similar in structure to Timer1 except that clock source of Timer2 comes from the system clock
“Fsys”/1.5. The system clock “Fsys” varies depending on the operation modes of the MCU.
The Timer2 consists of two 8-bit write-only preload registers T2H and T2L and 16-bit down counter. If
Timer2 is enabled, counter will decrement by one with each incoming clock pulse. Timer2 interrupt will
be generated when the counter underflows - counts down to FFFFH. And it will be automatically
reloaded with the value of T2H and T2L.
Please note that the interrupt signal is generated when counter counts from 0000H to FFFFH. If the value
of counter is N, and count down to FFFFH, the total count is N+1. The content of counter is zero when
system resets. Once it is enabled to count at this time, the interrupt will be generated immediately and
value of T2H and T2L will be loaded since the counter counts to FFFFH. So the T2H and T2L value
should be set before enabling Timer2.
The Timer2 related control registers are list as below:
