2.3.21
This pin is the power input for the input comparator of the MCAN module.
2.3.22
This pin is the ground connection for the input comparator of the MCAN bus.
2.3.23
This pin provides the high voltage reference output for the MCAN bus. The output voltage is equal
to VDD 2.
2.3.24
These input pins connect the physical bus lines to the input comparator (receive). When the MCAN
is in SLEEP mode, a dominant level on these pins will wake it up.
2.3.25
These output pins connect the output drivers of the MCAN bus to the physical bus lines (transmit).
MCAN bus lines. The bus can have one of two complementary values: dominant or recessive.
During simultaneous transmission of dominant and recessive bits the resulting bus value will be
dominant. For example with a positive logic wired-AND implementation of the bus, the dominant
level would correspond to a logic 0 and the recessive level to a logic 1.
