Datasheet - Detailed Description
Feature Register
(0x0E)
The Feature Register is used for enabling various features including switching the device into external clock mode,
applying an external reset, selecting code-B or HEX decoding, enabling or disabling blinking, setting the blinking rate,
and resetting the blink timing.
Note:
At power-up the Feature Register is initialized to 0.

R/W
External clock active.
0 = Internal oscillator is used for system clock.
1 = Pin CLK of the serial interface operates as system clock input.
Resets all control registers except the Feature Register.
0 = Reset Disabled. Normal operation.
1 = All control registers are reset to default state (except the Feature
Register) identically after power-up.
Note:
The Digit Registers maintain their data.
Selects display decoding for the selected digits (
Table 8 on page 13
).
0 = Enable Code-B decoding (see
Table 9 on page 14
).
1 = Enable HEX decoding (see
Table 10 on page 14
).
Not used
Enables blinking.
0 = Disable blinking. 1 = Enable blinking.
Sets blink with low frequency (with the internal oscillator enabled):
0 = Blink period typically is 1 second (0.5s on, 0.5s off).
1 = Blink period is 2 seconds (1s on, 1s off).
Synchronizes blinking on the rising edge of pin LD/CS. The multiplex
and blink timing counter is cleared on the rising edge of pin LD/CS. By
setting this bit in multiple devices, the blink timing can be synchronized
across all the devices.
Start Blinking with display enabled phase. When bit D4 (blink_en) is set,
bit D7 determines how blinking starts.
0 = Blinking starts with the display turned off.
1 = Blinking starts with the display turned on.
