What information can I obtain using I2C from the P2020 in slave mode? I see an ACK after a start bit and calling address. I'm not sure what registers are available with the 8 bit data byte. Do I
register address to read
read value of register?
I'm setting up the I2C registers through the eLBC with CPU. I thought maybe it only stored data in I2Cdata register, but that doesn't seem useful. Maybe slave mode is very limited.
