Hello Team


Could you check the question of MCP577C MCAN?


When I checked the 41.3.3 Data Bit Timing and Prescaler Register (M_CAN_DBTP) on 5777C RM Rev.7, I found the below mention.

The CAN bit time may be programed in the range of 4 to 49 time quanta.


As my known, thq above mention's means that 4~49 means the sum of [DTSEG1 + DTSEG2 + 3]…

However the minimum value of DTSEG1 and DTSEG2 is “0”…..

So the programed in the range is possible to 3 to 49…([0 + 0 + 3] ~ [ 0x1f + 0xf + 3]) if I use the below register information.


Could you check this question?



Thank you.
