11 / 66 page Si11 41/42/43 Preliminary Rev. 0.5 11 Figure 4. Typical Ambient Light Sense Performance Curves (Preliminary) 2.4. Host Interface The host interface to the Si1141/42/43 consists of three pins: SCL SDA INT SCL and SDA are standard open-drain pins as required for I2C operation. The Si1141/42/43 asserts the INT pin to interrupt the host processor. The INT pin is an open-drain output. A pull-up resistor is needed for proper operation. As an open-drain output, it can be shared with other open-drain interrupt sources in the system. For proper operation, the Si1141/42/43 is expected to fully complete its Initialization Mode prior to any activity on the I2C. The INT, SCL, and SDA pins are designed so that it is possible for the Si1141/42/43 to enter the Off Mode by software command without interfering with normal operation of other I2C devices on the bus. The Si1141/42/43 I2C slave address is 0x5A. The Si1141/42/43 also responds to the global address (0x00) and the global reset command (0x06). Only 7-bit I2C addressing is supported; 10-bit I2C addressing is not supported. Conceptually, the I2C interface allows access to the Si1141/42/43 internal registers. Table 15 on page 25 is a summary of these registers. An I2C write access always begins with a start (or restart) condition. The first byte after the start condition is the I2C address and a read-write bit. The second byte specifies the starting address of the Si1141/42/43 internal register. Subsequent bytes are written to the Si1141/42/43 internal register sequentially until a stop condition is encountered. An I2C write access with only two bytes is typically used to set up the Si1141/42/43 internal address in preparation for an I2C read. The I2C read access, like the I2C write access, begins with a start or restart condition. In an I2C read, the I2C |
