Table 12. Power-Up Configuration
*When reading from the global registers, only the master MAX6960 (whose driver address is 0x00) responds.
Table 13. Global Driver Devices Format
Table 14. Global Driver Rows Format
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).
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.
