(13) CAN stop register (CSTOP)
The CSTOP register controls clock supply to the entire CAN system.
This register can be read/written in 16-bit units.
Cautions 1. Be sure to set the CSTP bit (to 1) if the FCAN function will not be used.
2. When the CSTP bit has been set (to 1), access to FCAN registers other than the CSTOP
register is prohibited. Access to FCAN (other than the CSTOP register) is possible only
when the CSTP bit has not been set (to 1).
3. When a change occurs on the CAN bus via a CSTP bit setting while the clock supply to
the CPU or peripheral functions is stopped, CPU can be woken up.
4. If the CAN main clock (f
module to initial mode (INIT bit of C1CTRL register = 1), clear (0) the GOM bit of the
CGST register, and then set (1) the CSTP bit.
