TMHMD0
Be sure to set the count clock so that the following condition is satisfied.
Note the following points when selecting the TM50 output as the count clock.
It is not necessary to enable the TO50 pin as a timer output pin in any mode.

Start the operation of 8-bit timer/event counter 50 first and then set the count clock to make the duty
= 50%.
Mode in which the count clock is cleared and started upon a match of TM50 and CR50 (TMC506 =
0)
Start the operation of 8-bit timer/event counter 50 first and then enable the timer F/F inversion
operation (TMC501 = 1).
