I2C PROGRAMMING AND DIGITAL CONTROL

The ADP8860 provides full software programmability to

facilitate its adoption in various product architectures. The

default I2C address is 0101010x (x = 0 during write, x = 1 during

read). Therefore, the default write address is 0x54 and the read

address is 0x55.

Note the following general behavior of registers:

•

All registers are set to their default values during reset or

after a UVLO event.

•

All registers are read/write unless otherwise specified.

•

Unused bits are read as zero.

The following tables provide register and bit descriptions. The

reset value for all bits in the bit map tables is all 0s, except in

Table 9 (see Table 9 for its unique reset value). Wherever the

acronym N/A appears in the tables, it means not applicable.
