Terms.emf
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.
