MSCAN filter uses three sets of registers to provide the filter configuration. Firstly, the CANIDAC register
determines the configuration of the banks into filter sizes and number of filters. Secondly, registers
CANIDMR0/1/2/3 determine those bits on which the filter will operate by placing a ‘0’ at the appropriate
