MISC1: Miscellaneous Control Register 1
Address = 09h
BIT 7
BIT 6
BIT 5
BIT 4
BIT 3
BIT 2
BIT 1
BIT 0
0
1
0
This register controls the miscellaneous functionality. For the ADS1191 and ADS1192 devices, 02h must be
written to the MISC1 register.
Bits[7:2]
Must be set to '0'
Bit 6
Must be set to '1'
Bit 0
Must be set to '0'
MISC2: Miscellaneous Control Register 2
Address = 0Ah
BIT 7
BIT 6
BIT 5
BIT 4
BIT 3
BIT 2
BIT 1
BIT 0
CALIB_ON
0
RLDREF_INT
0
This register controls the calibration functionality.
Bit 7
CALIB_ON: Calibration on
This bit is used to enable offset calibration.
0 = Off (default)
1 = On
Bits[6:2]
Must be '0'
Bit 1
RLDREF_INT: RLDREF signal
This bit determines the RLDREF signal source.
0 = RLDREF is external (default)
1 = RLDREF is fed internally
Bit 0
Must be set to '0'
GPIO: General-Purpose I/O Register
Address = 0Bh
BIT 7
BIT 6
BIT 5
BIT 4
BIT 3
BIT 2
BIT 1
BIT 0
0
GPIOC2
GPIOC1
GPIOD2
GPIOD1
This register controls the GPIO pins.
Bits[7:4]
Must be '0'
Bits[3:2]
GPIOC[2:1]: GPIO 1 and 2 control
These bits determine if the corresponding GPIOD pin is an input or output.
0 = Output
1 = Input (default)
Bits[1:0]
GPIOD[2:1]: GPIO 1 and 2 data
These bits are used to read and write data to the GPIO ports.
When reading the register, the data returned correspond to the state of the GPIO external pins, whether they are
programmed as inputs or as outputs. As outputs, a write to the GPIOD sets the output value. As inputs, a write to the
GPIOD has no effect.
