8.1.5 READ128

Figure 19 illustrates the format of the frame and the command.

Figure 19. Frame Organization of the READ128 Command

The command is composed by a first frame transmitted to the AS5263. The device is in slave communication mode. The device remains for the

the SFRs. The numbering of the data bytes correlates with the address of the related SFR.

An even parity bit is used to guarantee a correct data transmission. Each parity (P) is related to the frame data content of the 16 bit word. The

MSB of the CMD dummy (P) is reserved for the parity information.
