15.2.19 Message Data (MD0 to MD15)
The message data register sets (MD0 to MD15) consist of eight 8-bit readable/writable registers
(MDx[1] to MDx[8]). The HCAN has 16 sets of these registers (MD0 to MD15).
The initial value of these registers is undefined, so they must be initialized (by writing 0 or 1).
15.2.20 Module Stop Control Register C (MSTPCRC)
MSTPCRC is an 8-bit readable/writable register that performs module stop mode control.
When the MSTPC3 bit is set to 1, HCAN operation is stopped at the end of the bus cycle, and
module stop mode is entered. Register read/write accesses are not possible in module stop mode.
For details, see section 22.5, Module Stop Mode.
MSTPCRC is initialized to H'FF by a reset, and in hardware standby mode. It is not initialized in
software standby mode.
Bit 3—Module Stop (MSTPC3): Specifies the HCAN module stop mode.
