I would like to know how to calculate acceptance filter and mask values for extended IDs in KEA128 MCU
Hi,
There are two banks of CAN receiver ID acceptance filter as the rectangle registers which can function for Extended ID filter(29 bits) and standard ID filter(11 bits). The MSCAN_CANIDARn is the ID that the CAN module wants to accept, the MSCAN_CANIDMRn include the mask bit.
The MSCAN_CANIDAC[IDAM] defines the filter mode.
For the acceptance pls refer to section 32.4.5 Identifier acceptance filter
Hope it can help you
