The S bit in the configuration register selects shutdown
or normal operation (Table 7). The display driver can be
programmed while in shutdown mode, and shutdown
mode is overridden when in display test mode. For nor-
mal operation, the S bit should be set to 1.
The B bit in the configuration register selects the blink
rate. This is the speed that the segments alternate

between plane P0 and plane P1 refresh data. The blink
rate is determined by the frequency of the multiplex clock
OSC, in addition to the setting of the B bit (Table 8).
The E bit globally enables or disables the blink feature
of the device (Table 9). When blink is globally enabled,
then the digit data in both planes P0 and P1 are used
to control the display (Table 10).
