Figure 12.18
A CAN0 wake-up interrupt request is generated by a falling edge of the CRX pin. The CAN0 wake-up interrupt is
enabled when the PortEn bit is 1 (CTX/CRX function) and Sleep bit is 1 (Sleep mode enabled) in the C0CTLR
register.
Figure 12.18 shows the Block Diagram of CAN0 Wake-Up Interrupt.
