Is this a typo?

In the datasheet of AD9545 RevB, page 153, on about "Register Transfer Instructions (0x00 to 0x7F)" it say :  ... where the first byte to follow the data instruction is the most significant byte of the register address, I think it should be:  ... where the first byte to follow the data instruction is the least significant byte of the register address.

Please confirm this.

    HI,

    the protocol of the EEPROM content is as follows:

    EEPROM ADDRESS

    Byte Value (hex)

    X

    N-1, N is the number of consecutive bytes starting at address X

    X+1

    LSB Address of First Byte in the batch

    X+2

    MSB Address of First Byte in the batch

    X+3,….,X+2+N

    Byte Content

    You are right: the data instruction is the number N-1 and it is followed by the least significant byte of the address of the first byte in the batch.

    I'll make a note to correct this when we will review the data sheet.
