Normal mode 1
In contrast to biphase mode the bit representation is time invariant and not toggled.
Normal mode 2
For the TX0 pin this is the same as normal mode 1, however the data stream to TX1 is replaced
by the transmit clock. The rising edge of the transmit clock marks the beginning of a bit time. The
clock pulse will be t
Other output control bits
The other six bits in this register control the output driver configurations, to determine the format
of the output signal for a given data value (see
OCTP0/1 – These two bits control whether the P-type output control transistors are enabled.
OCTN0/1 – These two bits control whether the N-type output control transistors are enabled.
OCPOL0/1 – These two bits determine the driver output polarity for each of the MCAN bus lines
(TX0, TX1).
TP0/1 and TN0/1 – These are the resulting states of the output transistors.
TD – This is the internal value of the data bit to be transferred across the MCAN bus. (A zero
corresponds to a dominant bit, a one to a recessive.)
The actions of these bits in the output control register are as shown in
