Example of Phase Counting Mode Setting Procedure: Figure 11.25 shows an example of the
phase counting mode setting procedure.
Examples of Phase Counting Mode Operation: In phase counting mode, TCNT counts up or
down according to the phase difference between two external clocks. There are four modes,
according to the count conditions.
1. Phase counting mode 1
TCLKA (channels 1 and 5 * )
TCLKC (channels 2 and 4 * )
TCLKB (channels 1 and 5 * )
TCLKD (channels 2 and 4 * )
Note: * Not available in the H8S/2227 Group.
Figure 11.26 shows an example of phase counting mode 1 operation, and table 11.32
summarizes the TCNT up/down-count conditions.
