Manufacturer:ST Description:Input bus select / I2C clock input. The operation of this pin depends on whether the I2C interface is enabled or disabled. This pin is only 3.3-V tolerant. When I2C is disabled (ISEL = low), a high level selects 24-bit input, single-edge input mode. A low level selects 12-bit input, dual-edge input mode. When I2C is enabled (ISEL = high), this pin functions as the I2C clock input (see the I2C register descriptions section). In this configuration, this pin has an open-drain output that requires an external 5-kΩ pullup resistor connected to VDD. DSEL/I2C data. The operation of this pin depends on whether the I2C interface is enabled or disabled. This pin is only 3.3-V tolerant. When I2C is disabled (ISEL = low), this pin is used with BSEL and VREF to select the single-ended or differential input clock mode (see the universal graphics controller interface modes section). When I2C is enabled (ISEL = high), this pin functions as the I2C bidirectional data line. In this configuration, this pin has an open-drain output that requires an external 5-kΩ pullup resistor connected to VDD. |
