In phase counting mode, external clock edge selection by bits CKEG1 and CKEG0 in 16TCR2
and counter clock selection by bits TPSC2 to TPSC0 are invalid, and the above phase counting
mode operations take precedence.
The counter clearing condition selected by the CCLR1 and CCLR0 bits in 16TCR2 and the
compare match/input capture settings and interrupt functions of TIOR2, TISRA, TISRB, TISRC
remain effective in phase counting mode.
Bit 5—Flag Direction (FDIR): Designates the setting condition for the OVF flag in TISRC. The
FDIR designation is valid in all modes in channel 2.

Bits 4 and 3—Reserved: These bits cannot be modified and are always read as 1.
Bit 2—PWM Mode 2 (PWM2): Selects whether channel 2 operates normally or in PWM mode.

When bit PWM2 is set to 1 to select PWM mode, pin TIOCA
output goes to 1 at compare match with GRA2, and to 0 at compare match with GRB2.
Bit 1—PWM Mode 1 (PWM1): Selects whether channel 1 operates normally or in PWM mode.
