• Manufacturer Part Number: h8s-2649
• Description: Renesas 16-bit Single-chip Microcomputer H8s Family/h8s/2600 Series
• Manufacturer: Renesas Electronics Corporation.

Stopping: When the CST bit in PWCR is cleared to 0, PWCNT is reset and stops. All PWM
outputs go low (or high if the corresponding bit in PWPR is set to 1).
16.5.2
Setting a corresponding bit in the PWM buffer transfer control register disables a buffer transfer
on compare match. This prevents the output from changing when compare match occurs while the
buffer register is being changed. A buffer transfer on compare match is resumed after cleaning the
bit.
