8.2.3
TMDR is an 8-bit readable/writable register that selects PWM mode for channels 0 to 2. It also
selects phase counting mode and the overflow flag (OVF) setting conditions for channel 2.
TMDR is initialized to H'98 by a reset and in standby mode.
Bit 7—Reserved: This bit cannot be modified and is always read as 1.
Bit 6—Phase Counting Mode Flag (MDF): Selects whether channel 2 operates normally or in
phase counting mode.

When MDF is set to 1 to select phase counting mode, 16TCNT2 operates as an up/down-counter
and pins TCLKA and TCLKB become counter clock input pins. 16TCNT2 counts both rising and
falling edges of TCLKA and TCLKB, and counts up or down as follows.
