CLR (TC4CR).3: Stops the timer.
CLR (TC4CR).7 : Sets the PWM4 pin to the high level.
Note 3: To enter the STOP mode, stop the timer and then enter the STOP mode. If the STOP mode is entered with-
out stopping of the timer when fc, fc/2 or fs is selected as the source clock, a pulse is output from the PWM4
pin during the warm-up period time after exiting the STOP mode.

Example :Generating a pulse with 1-ms high-level width and a period of 32.768 ms (fc = 16.0 MHz)
Setting ports
LDW
(PWREG3), 07D0H
: Sets the pulse width.
LD
(TC3CR), 33H
: Sets the operating clock to fc/2³, and 16-bit PWM output
mode (lower byte).
LD
(TC4CR), 056H
: Sets TFF4 to the initial value 0, and 16-bit PWM signal
generation mode (upper byte).
LD
(TC4CR), 05EH
: Starts the timer.
