Figure 2 Voltage and Current Definition

In all tables of electrical characteristics, symbols related to channels without channel number are valid for each

channel separately (e.g. VDS specification is valid for VDS1 â¦ VDS4).

All SPI register bits are marked as follows: ADDR.PARAMETER (e.g. HWCR.STB) with the exception of the bits in

the Diagnosis frames which are marked only with PARAMETER (e.g. VSMON).
