applied to the Sync pin (Pin 62). See the Synchronization section
for detailed explanations of the different modes.
External Address 4 Sleep
Bits in this register determine how the chip is programmed and
enables the channels. The program bits (D7:D4) must be set high
to
allow programming of CMEM and DMEM for each channel.
Sleep bits (D3:D0) are used to activate or sleep channels. These
can
be used manually by the user to bring up a channel by simply
writing
the required channel high. These bits can also be used in conjunc-
tion with the Start and Sync signals available in External Address
5 to synchronize the channels. See the Synchronization section for a
detailed explanation of different modes.
External Address 3:0 (Data Bytes)
These registers return or accept the data to be accessed for a
read or write to internal addresses

AD6623 and AD6622 Compatibility
The AD6623 functionality is a superset of the AD6622 functionality.
The AD6623 is pin-compatible with AD6622.
AD6622 compatibility is selected when bit 7 of Internal Control
Register 0x000 is low. In this state, all AD6623 extended control
registers are cleared. While in the AD6622 mode the unused
AD6623 pins are three-stated.
Listed below is the mapping of internal AD6623 registers. AD6622
compatibility is selected by setting
0x000:7 low.
In this state, all
AD6623 extended control registers are cleared. Registers marked
as
“
Reserved
”
must be written low.
