Table 44. Current Window filter Setting
Note: Times are indicated for 4 MHz f
The Current Window filter is activated each time
the PWM is turned ON. It blanks the output of the
current comparator during the time set by the
CFW[2:0] bits in the MCFR register. The reset val-
ue is 000b (blanking window off).
The Current feedback filter sets the number of
consecutive valid samples (when current is above
the limit) needed to generate the active CL event
used to turn OFF the PWM. The reset value is 1.
The sampling of the current comparator is done at

Table 45. Current Feedback Filter Setting
The ON time of the resulting PWM starts at the
end of the measurement window (rising edge),
and ends either at the beginning of the next meas-
urement window (falling edge), or when the cur-
rent level is reached.
Note: Be careful that the current comparator is
OFF until the CKE and/or DAC bits are set in the
MCRA register.
