System Control
(Continued)
When the part is configured as an I
2
C device then the LM4931 will respond to one of two addresses, according to theADDR input.
If ADDR is low then the address portion of the I
2
C transaction should be set to write to 0010000. When ADDR is high then the
address input should be set to write to 1110000. The LM4931 uses the following 11 registers to store configuration information:
