From Bq34z110 datasheet:
The LED/Comm Configuration register
Bits 0, 1, 2 are a code for one of five modes. 0 = No LED, 1 = Single LED, 2 = Four LEDs, 3 = External LEDs
with I2C comm, 4 = External LEDs with HDQ comm
Bits 4, 5, 6, and 7 are a binary code for number of external LEDs.
I am a little confused here: Can I use single Led mode and I2C communication or I should use external leds mode and 2 leds?
If I don't use the pins P4/SDA and P3/SCL for leds (only for I2C); can I use single led mode?
More than that is it possibile for me to use singe/four leds modes and I2C communication(without using SN74HC164) ?
