8.5.6
Feature Register (0xXE)
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, enabling or disabling the SPI-compatible interface (AS1106 only), setting the
blinking rate, and resetting the blink timing.
Note: At power-up the Feature Register is initialized to 0.

Feature Register
Enables and disables various device features.
Bit
Bit Name
Default
Access
Bit Description
External clock active.
D0
clk_en
0 R/W
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.
D1
reg_res
0 R/W
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.
D2
decode_sel
0 R/W
0 = Enable Code-B decoding (see Table 10 on page 10).
1 = Enable HEX decoding (see Table 11 on page 11).
Enables the SPI-compatible interface.
D3
spi_en
0 R/W
0 = Disable SPI-compatible interface (AS1106 only).
1 = Enable the SPI-compatible interface (AS1106 only).
Note: The SPI-compatible interface is always enabled in the AS1107.
Enables blinking.
D4
blink_en
0 R/W
0 = Disable blinking.
1 = Enable blinking.
Sets blink with low frequency (with the internal oscillator enabled):
D5
blink_freq_sel
0 R/W
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 LOAD/CSN. The multiplex and blink
D6
sync
0 R/W
timing counter is cleared on the rising edge of pin LOAD/CSN. By setting this bit in
multiple AS1106/AS1107 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
D7
blink_start
0 R/W
determines how blinking starts.
0 = Blinking starts with the display turned off.
1 = Blinking starts with the display turned on.
8.5.7
No-Op Register (0xX0)
The No-Op Register is used when multiple AS1106 or AS1107 devices are cascaded in order to support displays with more than 8 digits. The
cascading must be done in such a way that all DOUT pins are connected to DIN of the next AS1106/AS1107 (see Figure 14 on page 16). The
LOAD/CSN and CLK signals are connected to all devices.
For example, if five devices are cascaded, in order to perform a write operation to the fifth device, the write-command must be followed by four
no-operation commands. When the LOAD/CSN signal goes high, all shift registers are latched. The first four devices will receive no-operation
commands and only the fifth device will receive the intended operation command, and subsequently update its register.
