[1] IO: input/output; O: output; I: input; P: power supply; G: ground.
[2] GND1, GND2, GNDD and the exposed center pad of HVQFN44 package must be connected together on
the PCB; references in the data sheet to GND can be assumed to encompass GND1, GND2, GNDD and
the exposed center pad of HVQFN4 unless stated otherwise.
[3] VBUF1 and VBUF2 must be connected together on the PCB; note that references in the data sheet to VBUF
can be assumed to encompass VBUF1 and VBUF2 unless stated otherwise.
[4] VCC1 and VCC2 must be connected together on the PCB; note that references in the data sheet to VCC can
be assumed to encompass VCC1 and VCC2 unless stated otherwise.
[5] References in the data sheet to BM (e.g. pin BM or VBM) can be assumed to encompass BM_1 and BM_2
unless stated otherwise.
[6] References in the data sheet to BP (e.g. pin BP or VBP) can be assumed to encompass BP_1 and BP_2
unless stated otherwise.
