control registers remains unaltered. Shutdown can be
used to save power. For minimum supply current in
shutdown mode, logic inputs should be at ground or
V+ (CMOS-logic levels). The display driver can be pro-
grammed while in shutdown mode, and shutdown
mode can be overridden by the display test function.
Table 7 lists the blink rate selection format.
If blink is globally enabled by setting the E bit of the
configuration register (Table 8), then the digit data in
both planes P0 and P1 are used to control the display
(Table 9).

When the global blink timing synchronization bit is set,
the multiplex and blink timing counter is cleared on the
rising edge of CS. By setting the T bit in multiple
MAX6950/MAX6951s at the same time (or in quick suc-
cession), the blink timing can be synchronized across
all the devices.
When the global digit data clear (R data bit D5) is set,
the digit data for both planes P0 and P1 for ALL digits
is cleared on the rising edge of CS. Digits with decode
enabled display the zero. Digits without decode
enabled show all segments unlit.
