This register selects the format of frames handled by message slots corresponding to the respective bits in the
register. Setting any bit in this register to "0" selects the standard ID format, and setting any bit in this register to
"1" selects the extended ID format.
Note: • Settings of any bit in this register can only be changed when the corresponding slot does not
have transmit or receive requests set.
