ISL24211 Programming
The ISL24211 accepts I2C bus address and data when the WP
pin is high. The ISL24211 ignores the I2C bus when the WP pin is
low. Figure 10 shows the serial data format for writing the
register and programming the EEPROM. Figure 11 shows the
serial data format for reading the DAC register. Table 2 shows the
truth table for reading and writing the device.
Programming the EEPROM memory transfers the current DAC
register value to the EEPROM and occurs when the control bits
select the programming mode and the AVDD voltage is >10.8V.
After the EEPROM programming cycle is started, the WP pin can
be returned to logic low while the EEPROM write completes,
which takes a maximum of 100ms.
The ISL24211 uses a 6-bit I2C address, which is “100111yx” for
the first transmitted byte. Bit x is the R/W bit, and Bit y is the LSB
(D0) of the DCP register code to be written. The complete read
I2C Bus Signals
The ISL24211 uses fixed voltages for its I2C thresholds, rather
than the percentage of VDD described in the I2C specification
(see Table 3). This should not cause a problem in most systems,
but the I2C logic levels in a specific design should be checked to
ensure they are compatible with the ISL24211.
