Notes on Timer Input:
Figure 4.2 Timing of the timer input
*The external timer input such as CNTR0 and CNTR1 is taken in the evaluation MCU at the system clock falling
In this product, when the external input such as CNTR0 and CNTR1 is used for timer count source for Timer 1
and Timer2, the operation timing of the CNTR pin is different from that of an actual MCU because the CNTR
pin is the emulation port. Note that the set timing of timer interrupt request flag such as T1F and T2F is also
different.
Figure 4.2 shows that the operation timing when the external input such as CNTR0 and CNTR1 is used for
timer count source for Timer 1 and Timer 2.
Therefore, in this product, the timer external input frequency, f(CNTR), is limited to the maximum value shown
below:
f(CNTR): f(STCK)/6 x 0.9(Max)[Hz]
edge in the middle of the T2 state.
