This section describes in detail all the registers and register bits in the
MSCAN module. Each description includes a standard register diagram
with an associated figure number. Details of register bit and field
function follow the register diagrams, in bit order. All bits of all registers
in this module are completely synchronous to internal clocks during a
register read.
