It is not necessary to enable the TO50 pin as a timer output pin in any mode.
2. TMC506: Bit 6 of 8-bit timer mode control register 50 (TMC50)
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
PWM mode (TMC506 = 1)
Start the operation of 8-bit timer/event counter 50 first and then set the count clock to make the duty =
operation (TMC501 = 1).
