SPEED: Modulator Clock Speed
0 = fMOD = fOSC/128 (default)
1 = fMOD = fOSC/256
bit 4
BUFEN: Buffer Enable
0 = Buffer Disabled (default)
1 = Buffer Enabled
bit 3
BIT ORDER: Data Output Bit Order
0 = Most Significant Bit Transmitted First (default)
1 = Least Significant Bit Transmitted First
This configuration bit controls only the bit order
within the byte of data that is shifted out. Data is
always shifted out of the part most significant byte
first. Data is always shifted into the part most
significant bit first.

(default).
1 = Full-Scale Input Range equal to

NOTE: This allows reference voltages as high as
AVDD, but even with a 5V reference voltage the
calibration must be performed with this bit set to 0.

NOTE: The offset DAC must be enabled after calibration or the calibration
nullifies the effects.
DIO (Address 04H) Data I/O
Reset Value = 00H
If the IOCON register is configured for data, a value written
to this register appears on the data I/O pins if the pin is
configured as an output in the DIR register. Reading this
register returns the value of the data I/O pins.
Bit 4 to bit 7 is not used in ADS1240.
DIR (Address 05H) Direction Control for Data I/O
Reset Value = FFH
Each bit controls whether the corresponding data I/O pin is
an output (= 0) or input (= 1). The default power-up state is
as inputs.
Bit 4 to bit 7 is not used in ADS1240.
IOCON (Address 06H) I/O Configuration Register
Reset Value = 00H
bit 7-0
IO7: IO0: Data I/O Configuration
0 = Analog (default)
1 = Data
Configuring the pin as a data I/O pin allows it to be controlled
through the DIO and DIR registers.
Bit 4 to bit 7 is not used in ADS1240.
OCR0 (Address 07H) Offset Calibration Coefficient
(Least Significant Byte)
Reset Value = 00H
