Note:
Set the PRCR.PRC1 bit to 1 (write enabled) before rewriting this register.
Note 1. This bit should be rewritten while the oscillation of the clock to be controlled by this bit is stable. When entering software standby
mode after rewriting this bit, wait for two cycles of the CANMCLK after rewriting, and execute a WAIT instruction.
Note 2. This bit should be rewritten while the oscillation of the clock to be controlled by this bit is stable. The clock should be set for
oscillation when this bit is 0 (this module clock is enabled). When entering software standby mode after rewriting this bit, wait for
two cycles of the UCLK after rewriting, and execute a WAIT instruction. When stopping the clock after rewriting this bit to 1 (this
module clock is disabled), wait for two cycles of the UCLK after rewriting, and stop the clock.
