Selects the setting condition for the overflow
flag (OVF) in timer status register 2 (TSR2)
TMDR is initialized to H'80 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.
