GPIOC: GPIO CONFIGURATION REGISTER (Address = 07h)
7 6 5 4 3 2 1 0
CIO7 CIO6 CIO5 CIO4 CIO3 CIO2 CIO1 CIO0
Default = FFh.
This register configures the GPIO pins as inputs or as outputs. Note that the default configurations of the port
pins are inputs and as such they should not be left floating. See the GPIO Digital Port section.
0 = GPIO is an output; 1 = GPIO is an input (default).
CIO[7:0] GPIO Configuration
bit 7 CIO7, Digital I/O Configuration Bit for Pin GPIO7
bit 6 CIO6, Digital I/O Configuration Bit for Pin GPIO6
bit 5 CIO5, Digital I/O Configuration Bit for Pin GPIO5
bit 4 CIO4, Digital I/O Configuration Bit for Pin GPIO4
bit 3 CIO3, Digital I/O Configuration Bit for Pin GPIO3
bit 2 CIO2, Digital I/O Configuration Bit for Pin GPIO2
bit 1 CIO1, Digital I/O Configuration Bit for Pin GPIO1
bit 0 CIO0, Digital I/O Configuration Bit for Pin GPIO0
GPIOD: GPIO DATA REGISTER (Address = 08h)
7 6 5 4 3 2 1 0
DIO7 DIO6 DIO5 DIO4 DIO3 DIO2 DIO1 DIO0
Default = 00h.
This register is used to read and write data to the GPIO port pins. When reading this register, the data returned
corresponds 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. See the
GPIO Digital Port section.
0 = GPIO is logic low (default); 1 = GPIO is logic high.
DIO[7:0] GPIO Data
bit 7 DIO7, Digital I/O Data bit for Pin GPIO7
bit 6 DIO6, Digital I/O Data bit for Pin GPIO6
bit 5 DIO5, Digital I/O Data bit for Pin GPIO5
bit 4 DIO4, Digital I/O Data bit for Pin GPIO4
bit 3 DIO3, Digital I/O Data bit for Pin GPIO3
bit 2 DIO2, Digital I/O Data bit for Pin GPIO2
bit 1 DIO1, Digital I/O Data bit for Pin GPIO1
bit 0 DIO0, Digital I/O Data bit for Pin GPIO0
ID: DEVICE ID REGISTER (Address = 09h)
7 6 5 4 3 2 1 0
ID7 ID6 ID5 ID4 ID3 ID2 ID1 ID0
Default = 8Bh.
ID[7:0] ID Bits
Factory-programmed ID bits. Read-only.
Except for the ID4 bit, the ID byte can change at any time without notice.
ID4: 0= ADS1258, ADS1258-EP (24-Bit ADCs)
ID4: 1= ADS1158 (16-Bit ADC)
