I2C PROGRAMMING AND DIGITAL CONTROL

The ADP8863 provides full software programmability to facili-

tate its adoption in various product architectures. The I2C address

is 0101011x (x = 0 during write, x = 1 during read). Therefore,

the write address is 0x56 and the read address is 0x57.

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.

Table 8 to Table 84 provide register and bit descriptions. The

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

Table 10 (see Table 10 for its unique reset value). Wherever the

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