This allows the host to set up one or more registers in

consecutive MAX6960s with the display indirect address,

autoincrementing only when required (Table 10).

Driver Address Register

Reading the driver address register (Table 11) returns

the driver address that has been assigned to a particu-

lar MAX6960. The order of the driver addresses is

determined purely by the order that the 3-wire interface

is daisy-chained through multiple MAX6960s. The reg-

ister is used to detect the presence of a MAX6960 at an

address, and a binary search on the 256 possible

addresses can be used to determine the size of an

array of MAX6960s.

When reading from the global registers, only the master MAX6960 (whose driver address is 0x00) responds.
