Figure 42. Example - Power Bridge Waveform, PWM Up Brake Driving Mode
5.8.6 Register Description
The power section is controlled by the microcon-
troller through the following register:
POWER BRIDGE CONTROL STATUS REGIS-
TER (PBCSR)
Address: 0021h - Read/Write
Reset Value: 00000000
Bit 0
= EN:
Power Bridge enable. When reset the
bridge is disabled and OUTL and OUTR are in
high impedance condition.
Bit 1
= PWM_EN
: PWM driving enable. When reset
the bridge is driven directly by IN1 and IN2 bit (Di-
rect Mode). When set the driving is made by
PWM1 and/or PWM2 bit according to the Opera-
tion Mode selected by IN1 and IN2 bit.
Bit 2
= IN1
: Left Half Bridge control bit if
PWM_EN=0, driving mode selection bit if
PWM_EN=1.
Bit 3
= IN2
: Right Half Bridge control bit if
PWM_EN=0, driving mode selection bit if
PWM_EN=1.
The following table summarizes the driving mode
selection made by PWM_EN, IN1 and IN2 bit
Bit 4
= DIR
: Direction bit. This bit is meaningless
when PWM_EN=0. When PWM_EN is set the DIR
bit controls the “driving direction” of the bridge. In
order to implement a precise control of the direc-
tion changes, DIR value is latched by the rising
edge of the pwm signal driving the bridge. When
the signal does not have edges (i.e. pwm = 0% or
100%) the DIR bit can not be latched and the driv-
ing direction does not change even changing DIR
bit in BCSR.
Bit 5
= SC
: Short Circuit flag (read only)
Bit 6
= OVT
: Overtemperature flag (read only)
Bit 7
= PIE
: Power section interrupt enable.
