Product data sheet Rev. 1 — 13 November 2013 40 of 72 NXP Semiconductors PCF8545 Universal LCD driver for multiplex rates up to 1:8 9.2.8.1 Status read out Status read out for I2C-bus operation only. This command initiates the read-out of a fixed value plus the slave address bit A0 from the PCF8545. The read-out function allows the I2C master to confirm the existence of the device on the I2C-bus. If a readout is made, the R/W bit must be logic 1 and then the next data byte following is provided by the PCF8545 as shown in Figure 31. In the unlikely case that the chip has entered the internal test mode, detection of this state is possible by using the modified status read-out detailed in Table 29. The read out value is modified to indicate that the chip has entered an internal test mode. Fig 30. I2C-bus protocol write mode Table 28. Status read out value Bit Symbol Value Description 7 to 1 - 0101010 fixed value 0 A0 0 read back value is 01010100 1 read back value is 01010101 (1) From PCF8545. Fig 31. I2C-bus protocol read mode |
