Figure 18.6 shows the C0MCTLi Register.
CAN SFR Registers
Set the C0MCTLi register only w hen the CAN module is in CAN operation mode.
When w rite, set to 0. Each bit is set w hen the CAN module enters the respective state.
In Basic CAN mode, the RemActive bit serves as data format identification flag. When receiving a date frame, the
RemActive bit is set to 0 and w hen receiving a remote frame, the RemActive bit is set to 1.
One slot can not be defined as reception slot and transmission slot at the same time.
