Table 9. Register Address Local/Global Control Bit Format
Table 10. Register Address Autoincrement Control Bit Format
Table 11. Driver Address Register Format
The register map (Table 8) contains three local regis-
ters and eight global registers. Global registers are
always written to in all MAX6960s (on the same 4-wire
interface) at the same time, using a 16-bit transmission.
A read from a global register also always results in a
read from driver address 0. The global nature of these
registers ensures that all drivers work together, and
there is no chance of a software miss-send causing, for
example, multiple MAX6960s to try to transmit on the 4-
wire DOUT line at the same time.
The three local registers can be written to on an individ-
16
LOCAL: Only the MAX6960 indirected by driver
indirect address is written.
GLOBAL: All MAX6960s are written with the same
data.
LOCAL: The MAX6960 indirected by driver indirect
address responds.
GLOBAL: The MAX6960 configured to address 0x00
responds.
GLOBAL: All MAX6960s are written with the same
data.
GLOBAL: The MAX6960 configured to address 0x00
responds.
Driver indirect address is not changed
Driver indirect address is incremented after read/write

ual basis (updates just the MAX6960 indirected by the
global driver indirect address register), or on a global
basis (updates all MAX6960s), according to the status
of the local/global bit (Table 9). The local/global bit is
ignored during a 16-bit read transmission, and the
MAX6960 pointed to by the global driver indirect
address register is read.
When a read or write is indirected through the global dri-
ver indirect address register, the 16-bit command can
choose whether the global driver indirect address is
autoincremented after the command has been executed.
