(1) The device will recognize the I2C communication from a primary only during stand-by or continuous measure modes. While the device is in sleep mode, a valid secondary address will wake up the device but no acknowledge will be sent to the primary. Start up time must be considered before addressing the device after wake up.
(2) Add 25µs for each additional magnetic channel enabled for conversion with CONV_AVG = 000b. When CONV_AVG = 000b, the conversion time doesn't change with the T_CH_EN bit setting.
(3)
For conversion with CONV_AVG =101b, each channel data is collected 32 times. If an additional channel is enabled with CONV_AVG =101b, add 32×25µs = 800µs to the tmeasure to calculate the conversion time for two channels.
