C PROGRAMMING AND DIGITAL CONTROL
The ADP8860 provides full software programmability to
facilitate its adoption in various product architectures. The
default I

C 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.
