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.
