19.4 CAN SFR Registers
Figure 19.6 Registers C0MCTLj and C1MCTLj
Figures 19.6 to 19.11 show the CAN SFR registers.
NOTES:

1. As for write, only writing 0 is possible. The value of each bit is written when the CAN module enters the respective state.
2. In Basic CAN mode, slots 14 and 15 serve as data format identification flag.
3. One slot cannot be defined as reception slot and transmission slot at the same time.
4. This register cannot be set in CAN reset/initialization mode of the CAN module.
