10.2.8 Output Timing Control Registers
Output timing control register is used to control the timing of PWM pin output. Output timing variable function is
a function for pin output at any timing in 1 cycle of PWM. This register needs to be set only when double-buffer
mode is selected. The value of PWMDCNTn is loaded into the register at the timing selected with the PWM
mode control register (PWMMDn). When the PWM counter is not running, the double-buffer value is loaded into
the register as is regardless of the specified read timing.
This register needs to be set only when single-buffer mode is selected.

■ PWM1 Output Timing Control Register (PWMDCNT1: 0x0000A358) [8,16-bit Access Register]
