CONTROL REGISTERS
DEVICE ADDRESS
Following a start condition, the bus master must send the address
of the slave it is accessing. The slave address for the ADP5020 is
shown in Table 10. The Bit 0 defines the operation to be per-
Table 10. Slave Address
formed. When this bit is set to Logic 1, a read operation is
selected. When this bit is set to Logic 0, a write operation is
selected.
