AD9257
Rev. A | Page 31 of 40
MEMORY MAP REGISTER TABLE
The AD9257 uses a 3-wire interface and 16-bit addressing and,
therefore, Bit 0 and Bit 7 in Register 0x00 are set to 0, and Bit 3
and Bit 4 are set to 1. When Register 0x00, Bit 5 is set high, the
SPI enters a soft reset, where all of the user registers revert to
their default values and Bit 2 is automatically cleared.
