Section 8 16-Bit Timer
8.4.5
In phase counting mode the phase difference between two external clock inputs (at the TCLKA
and TCLKB pins) is detected, and 16TCNT2 counts up or down accordingly.
In phase counting mode, the TCLKA and TCLKB pins automatically function as external clock
input pins and 16TCNT2 becomes an up/down-counter, regardless of the settings of bits TPSC2 to
TPSC0, CKEG1, and CKEG0 in 16TCR2. Settings of bits CCLR1, CCLR0 in 16TCR2, and
settings in TIOR2, TISRA, TISRB, TISRC, setting of STR2 bit in TSTR, GRA2, and GRB2 are
valid. The input capture and output compare functions can be used, and interrupts can be
generated.
Phase counting is available only in channel 2.
Sample Setup Procedure for Phase Counting Mode: Figure 8.29 shows a sample procedure for
setting up phase counting mode.
