====== 7-Segment Display - Binary Interface ======

The four 7-segment displays can jointly display a 16-bit value as a four digit HEX number. \\
In this mode the display can't be switched off, use the [[7segment_raw|segment control interface]] instead. \\ \\

> Supported [[ctboard:mode_switch|modes]]: **1**, **2**, **3**, **4**

===== Registers =====

The registers are read / write.

===== Programming Example =====

The code snippet below shows how to use the 7-segment display as HEX display.

<code c>
#include "reg_ctboard.h"

CT_SEG7->BIN.BYTE.DS1_0 = (uint8_t) data_byte;        /* Write byte of binary data to DS1..0. */
CT_SEG7->BIN.HWORD = (uint16_t) data_halfword;        /* Write half word of binary data to all displays. */
</code>
\\

<code asm>
ADDR_SEG7_BIN   EQU      0x60000114

                LDR      r0, =ADDR_SEG7_BIN
                STRB     r1, [r0, #0]                     ; Write byte of binary data to DS1..0.
                STRH     r1, [r0, #0]                     ; Write half word of binary data to all displays.
