WebDebugging via CAN Overview There are two tool interfaces that are using MCMCAN: › DAP over CAN Physical Layer (DXCPL) › DAP over CAN Messages (DXCM) The main use case for DXCPL is the analysis of field returns. DXCPL is using DAP telegrams wrapped in CAN messages. Once DXCPL is activated, the CAN node is disconnected from the CAN bus. WebI tried setting BRPR =6, TS1 = 12, TS2 = 1, SJW = 0 (1 less for TS1, TS2, SJW as per product guide) for 250Kbps speed at 24MHz and have selected in PCAN view also the same settings (24MHz & 250Kbps). Are these values correct? How to calculate bitrate depending on clock, prescalar and time segment values. Regards, Bhavin
