The power-up sequence consists of an internal power-on
reset (POR), assertion of the external reset input RST,
and auto-address configuration (see the Local 3-Wire
Interface section). The internal POR resets all control
registers to the default values shown in Table 12.
After RST goes high an internal timer delays execution of
the auto-address configuration for 2
cycles (nominally 250ms at OSC = 4.194MHz) (see the
3-Wire Interface Clock (ADDCLK) section). During this
delay time, the global driver devices register (0x0E),
global driver rows register (0x0F), and global panel con-
figuration register (0x0D) should be written as these

values are used in the auto-address configuration
sequence (see the Device Configuration section). After
the internal delay time, the auto-addressing configuration
commences and takes a fixed interval of 256 ADDCLK
cycles to complete where the ADDCLK frequency is
OSC/4 (see the 3-Wire Interface Clock (ADDCLK) sec-
tion). After completing the auto-self-addressing of all
possible 256 interconnected devices, all of the
MAX6960s enter shutdown mode.
All registers are capable of write device register opera-
tions during the internal delay interval using the 4-wire
serial interface. Read device register operations are not
allowed during auto-address configuration.
