Pull-up is enabled if bit SIM = 1 (SPI 3-wire) in reg 12h. Default: Input without pull-up. Pull-up is enabled if bit SIM = 1 (SPI 3-wire) in reg 12h. SA0 I2C least significant bit of the device address (SA0) I2C least significant bit of the device address (SA0) 2 SDx Connect to VDDIO or GND I2C serial data master (MSDA) Default: input without pull-up. Pull-up is enabled if bit PULL_UP_EN = 1 in reg 1Ah. Default: input without pull-up. Pull-up is enabled if bit PULL_UP_EN = 1 in reg 1Ah. 3 SCx Connect to VDDIO or GND I2C serial clock master (MSCL) Default: input without pull-up. Pull-up is enabled if bit PULL_UP_EN = 1 in reg 1Ah. Default: input without pull-up. Pull-up is enabled if bit PULL_UP_EN = 1 in reg 1Ah. 4 INT1 Programmable interrupt 1 Programmable interrupt 1 Default: Output forced to ground Default: Output forced to ground 5 Vdd_IO Power supply for I/O pins Power supply for I/O pins 6 GND 0 V supply 0 V supply 7 GND 0 V supply 0 V supply 8 Vdd Power supply Power supply 9 INT2 Programmable interrupt 2 (INT2) / Data enabled (DEN) Programmable interrupt 2 (INT2) / Data enabled (DEN) / I2C master external synchronization signal (MDRDY) Default: Output forced to ground Default: Output forced to ground 10 NC Leave unconnected(1) Leave unconnected(1) Leave unconnected(1) Leave unconnected(1) 11 NC Leave unconnected(1) Leave unconnected(1) Leave unconnected(1) Leave unconnected(1) 12 CS I2C/SPI mode selection (1:SPI idle mode / I2C communication enabled; 0: SPI communication mode / I2C disabled) I2C/SPI mode selection (1:SPI idle mode / I2C communication enabled; 0: SPI communication mode / I2C disabled) Default: Input with pull-up. Pull-up is disabled if bit I2C_disable = 1 in reg 13h. Default: Input with pull-up. Pull-up is disabled if bit I2C_disable = 1 in reg 13h. |
