Global Blink Enable/Disable (E Data Bit D3) Format
The E bit globally enables or disables the blink feature
of the device (Table 10). When blink is globally
enabled, then the digit data in both planes P0 and P1
are used to control the display (Table 11).
When blink is globally disabled, then only the digit data
in plane P0 is used to control the display. The digit data
in plane P1 is ignored.
Global Blink Timing Synchronization (T Data Bit D4)
Format
By setting the T bit in multiple MAX6953s at the same
time (or in quick succession), the blink timing can be
synchronized across all the devices (Table 12). Note
that the display multiplexing sequence is also reset,
which might give rise to a one-time display flicker when
the register is written.
