IFx Data A and Data B Registers (IFxDTA1n, IFxDTA2n,
IFxDTB1n, IFxDTB2n)
The data bytes of CAN messages are stored in the IFx Message Buffer Registers.
■ IFx Data A and Data B Registers (IFxDTAn, IFxDTBn)
In a CAN Data Frame, Data(0) is the first, Data(7) is the last byte to be transmitted or received. In CAN's
serial bit stream, the MSB of each byte will be transmitted first.
The data bytes of CAN messages are stored in the IFx Message Buffer Registers in the following order:
