NOTES:
1. Set the MCD register after the PRC0 bit in the PRCR register is set to 1 (write enable).
2. When stop mode or low-power consumption mode is entered, bits MCD4 to MCD0 become 01000b.
3. When the PM24 bit in the PM2 register is set to 0 (clock selected by the CM07 bit), access the CAN-associated registers after
In on-chip oscillator mode, bits MCD4 to MCD0 do not become 01000b even if the CM05 bit in the CM0 register is set to 1 (main
clock stops).
bits MCD4 to MCD0 are set to 10010b.
