====== 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. \\ \\

===== 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. */

.equ ADDR_SEG7_BIN,  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.
