Question of MCP577C MCAN

[Luke_Chun]

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.

Hi Luke,

I assume one of the DTSEG1 or DTSEG2 could have valid value from 1, but let me check this with Apps.

Hello PetrS‌

Could you check my question?

As my checking on MPC5777C RM Rev.7, it is showing min value = 0 both DTSEG1 and DTSEG2. 

Thank you.
