RDATA–Read Data
Description: Read the most recent conversion result from the
Data Output Register (DOR). This is a 24-bit value.
Operands:
None
Bytes:
1
Encoding:
0000 0001
Data Transfer Sequence:
RDATAC–Read Data Continuous
Description: Read Data Continuous mode enables the con-
tinuous output of new data on each DRDY. This command
eliminates the need to send the Read Data Command on each
DRDY. This mode may be terminated by either the STOPC
command or the RESET command. Wait at least 10 fOSC after
DRDY falls before reading.
Operands:
None
Bytes:
1
Encoding:
0000 0011
Data Transfer Sequence:
Command terminated when “uuuu uuuu” equals STOPC or
RESET.

TABLE IV. Command Summary.
The commands listed in Table IV control the operations of
the ADS1240 and ADS1241. Some of the commands are
stand-alone commands (e.g., RESET) while others require
additional bytes (e.g., WREG requires the count and data
bytes).
Operands:
n = count (0 to 127)
r = register (0 to 15)
x = don’t care
