31:0 | 0h | RW/V | Flash Data (FD) This field is shifted out as the SPI Data on the MOSI Data pin during the data portion of the SPI cycle. This register also shifts in the data from the MISO pin into this register during the data portion of the SPI cycle. The data is always shifted starting with the least significant byte, msb to lsb, followed by the next least significant byte, msb to lsb, etc. Specifically, the shift order on SPI in terms of bits within this register is: 7-6-5-4-3-2-1-0-15-14-13- ... 8-23-22- ... 16-31 ... 24 Bit 24 is the last bit shifted out/in. There are no alignment assumptions; byte 0 always represents the value specified by the cycle address. |
