Figures 23.3 to 23.18, and Figures 23.20 to 23.33 show registers associated with CAN. To access the
CAN-associated registers, set the CM21 bit in the CM2 register to "0" (main clock or PLL clock as CPU
clock) and the MCD4 to MCD0 bits in the MCD register to "10010
in the PM2 register to "1" (main clock direct mode) and the PM25 bit in the PM2 regiseter to "1" (CAN clock).
Two wait states are added into the bus cycle.
Refer to 7. Processor Mode and 9. Clock Generation Circuit.
