VDD
Power
Logic outputs supply voltage (pull-up reference)
6VREG
Power
Internal 3 V voltage regulator output and 3.3 V external
logic supply
7
OSCIN
Analog input
Oscillator pin 1. To connect an external oscillator or clock
source. If this pin is UNUSED, it should be connected to
ground.
8
OSCOUT
Analog output
Oscillator pin 2. To connect an external oscillator. When
the internal oscillator is used this pin can supply a
2/4/8/16 MHz. If this pin is UNUSED, it should be left
floating.

VBOOT
Supply voltage
Bootstrap voltage needed for driving the high side power
DMOS of both bridges (A and B)
5
ADCIN
Analog input
Internal analog to digital converter input
