Data Sheet
Rev. 0 | Page 34 of 40
MEMORY MAP REGISTER TABLE
The AD9653 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 Bit 5 in Register 0x00 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.
