5.3.12
DB7 – DB0 — data bits
These data bits in the eight data segment registers make up the bytes of data to be transmitted.
The number of bytes to be transmitted is determined by the data length code.
5.3.13
The layout of this register is identical to the TBI register (see
(Note that there are actually two receive buffer register sets, but switching between them is
handled internally by the MCAN.)
