TMHMD0
Set the count clock to satisfy the following conditions.
• V
• V
• V
• V
When selecting the TM50 output as the count clock, note the following.
• PWM mode (TMC506 = 1)
• Mode in which clear & start occurs on a match of TM50 and CR50 (TMC506 = 0)
In the both modes, it is not necessary to enable the timer output for the TO50 pin.
Address: FF69H
Set the clock to the 50% duty and start the 8-bit timer/event counter 50 operation beforehand.
Enable the timer F/F inversion operation (TMC501 = 1) and start the 8-bit timer/event counter 50
operation beforehand.
