Interrupt generation
Interrupt generation is controlled by PDIE bit in BCSR register. When this bit is set
Overtemperature and Short-circuit conditions generate an interrupt as described in
Section
Setting PDIE when SC and/or OVT flag are set, immediately generates an interrupt request.
The interrupt request of the power bridge is cleared when the EN bit is cleared by software.
Operating Modes
The status of the OUTL and OUTR power outputs is controlled by IN1, IN2, EN, PWM_EN
and DIR bit in BCSR register, plus the PWM1 and PWM2 line, according to the Functional
Description Table
The functional description table
(Down Left or Right) to indicate the driving signal of the four DMOS. Conventionally a
transistor is in the on status when its driving signal is set (‘1’) while it is in off status when the
driving signal is reset (‘0’).
