Count Source
The method of selecting the count source is common to all modes.
Table 19.5 lists the Count Source Selection, and Figure 19.2 shows a Count Source Block Diagram.
The pulse width of the external clock input to the TRCCLK pin should be three cycles or more of the timer RC
operation clock (refer to Table 19.1 Timer RC Operation Clock).
To select fOCO40M or fOCO-F as the count source, set the FRA00 bit in the FRA0 register set to 1 (high-speed
on-chip oscillator on), and then set bits TCK2 to TCK0 in the TRCCR1 register to 110b (fOCO40M) or 111b
(fOCO-F).
