The CAN clock is an operating clock for the CAN module. f1 is selected as the CAN clock when the PM25 bit
in the PM2 register is set to 0. fCAN is selected as the CAN clock when the PM25 bit is set to 1. Set the PM25
bit while the SLEEP bit in CiSLPR register (i = 0, 1) is set to 0 (sleep mode).
Follow the procedure below before accessing the CAN-associated registers.
Do not enter wait mode or stop mode when the PM24 bit is set to 1.
NOTE:
1. The wait time to switch clock varies depending on the CPU clock frequency before and after the PM24 bit
CAN Clock and CPU Clock
•
(1) Set the PM24 bit to 0 (CPU clock is selected by the CM07 bit).
(2) Set the CM21 bit in the CM2 register to 0 (CPU clock is selected by the CM17 bit).
(3) Set bits MCD4 to MCD0 to 10010b (no division).
(4) Set the PM13 bit in the PM1 register to 1 (2 wait states).
•
(1) Set the PM24 bit to 1 (CPU clock is selected by the CM07 bit).
(2) Set the PM13 bit in the PM1 register to 1 (2 wait states).
(3) Wait for the time to switch clock.
•
•
When the PM25 bit is set to 0 (f1):
When the PM25 bit is set to 1 (fCAN):
High frequency: Higher frequency compared “before the PM24 bit changes” with “after the PM24 bit
changes”
Low frequency: Lower frequency compared “before the PM24 bit changes” with “after the PM24 bit
changes”
is changed.
