10.4.6
In phase counting mode, the phase difference between two external clock inputs is detected and
TCNT counts up or down accordingly. This mode can be set for channels 1 and 2.
When phase counting mode is set, an external clock is selected as the counter input clock and
TCNT operates as an up/down-counter regardless of the setting of bits TPSC0 to TPSC2 and bits
CKEG0 and CKEG1 in TCR. However, the functions of bits CCLR0 and CCLR1 in TCR, and of
TIOR, TIER, and TGR, are valid, and input capture/compare match and interrupt functions can be
used.
This can be used for two-phase encoder pulse input.
If overflow occurs when TCNT is counting up, the TCFV flag in TSR is set; if underflow occurs
when TCNT is counting down, the TCFU flag is set.
The TCFD bit in TSR is the count direction flag. Reading the TCFD flag reveals whether TCNT is
counting up or down.
Table 10.32 shows the correspondence between external clock pins and channels.
Table 10.32 Phase Counting Mode Clock Input Pins
Example of Phase Counting Mode Setting Procedure: Figure 10.24 shows an example of the
phase counting mode setting procedure.
