The HCAN is provided with an HCAN sleep mode that places the HCAN module in the sleep
state to reduce current dissipation. Figure 15.11 shows a flowchart of the HCAN sleep mode.
unread interrupt flag (IRR9) in the interrupt mask register (IMR) is set to the interrupt enable
value at this time, an interrupt can be sent to the CPU. Figure 15.10 shows a flowchart of
unread message overwriting.
