93 / 113 page  91 ATXP032 DS-ATXP032–114I–4-2020 Note also that in DDR mode, the SFDP command can only be used for addressing data on a 32-bit (4-byte) boundary. (Address bits A 1 and A0 both have to be 0). After the three address bytes and the dummy cycles have been clocked in, additional clock cycles will result in data being output on the I/O pin(s). The data is always output with the MSB of a byte first. When the last byte (0000FFh) of the SFDP security register has been read, the device continues reading back at the beginning of the register (000000h). No delays are incurred when wrapping around from the end of the register to the beginning of the register. Deasserting the CS pin terminates the read operation and places the I/O pin(s) into a high-impedance state. The CS pin can be deasserted at any time and does not require that a full byte of data be read. The format of the SFDP register follows the format provided in JEDEC Standard No. 216 Rev D.
