Bits 7:4 = DS[3:0]: Delay for sampling at Ton
These bits are used to define the delay inserted
before sampling in order to sample during PWM
ON time.

Note: Times are indicated for 4 MHz f
Bit 3 = SOI Sampling Out Interrupt flag.
This interrupt indicates that the sampling that
should have been done during Ton has occured

carded.
0: No Sampling Out Interrupt Pending
1: Sampling Out Interrupt Pending
Bit 2 = SOM: Sampling Out Mask bit.
This interrupt is available only for Z event sampling
as D event sampling is always done at f
frequency.
0: Sampling Out interrupt disabled
1: Sampling Out interrupt enabled
This interrupt is available only when a delay has
been set in the DS[3:0] bits in the MCONF register.
Note: It is recommended to disable the sampling
out interrupt when software Z event is enabled (SZ
bit in MCRC register is set) and if the value in the
DS[3:0] bits is modified to change the sampling
method during the application.
