18.10 Initial Settings
The CAN module initializes the CAN RAM after the operation of the CAN module is enabled. The RAM initialization
time is 276 cycles of f
CLK. The GRAMINIT flag in the GSTS register is set to 1 (CAN RAM initialization is ongoing) during
the RAM initialization and is cleared to 0 (CAN RAM initialization is finished) when the initialization is completed. Make
CAN settings after the GRAMINIT flag is cleared to 0.
Figure 18-16 shows the CAN setting procedure after the operation of the CAN module is enabled.
