7.4 Operation
7.4.1 FRC Incrementation Timing
The FRC increments on a pulse generated once for each cycle of the selected (internal or external)
clock source.
(1) Internal Clock Sources: Can be selected by the CKS1 and CKS0 bits in the TCR. Internal
clock sources are created by dividing the system clock (Ø). Three internal clock sources are
available: Ø/2, Ø/8, and Ø/32. Figure 7-4 shows the increment timing.
