Notes: . Peripheral units  and  cannot be driven simultaneously. To drive them continu-
ously, set the duty cycle ratio to 0% or less (excluding an externally connected
buzzer). Refer to the separate Specifications Manual for details.
. The following external buzzer is available as an option.
External buzzer model: RMB-4
