Figure 2 Terms of TLE7231G
In all tables of electrical characteristics is valid: Channel related symbols without channel number are valid for each
channel separately (e.g.
V
DS
specification is valid for V
DS0
… V
DS3
).
All SPI register bits are marked as follows: PARAMETER (e.g. IN0). In SPI register description, the values in bold
letters (e.g. 0) are default values.
