-====== 7 Segment Display ======
+====== 7-Segment Display ======
-There are 4 7 segment displays mounted on the CT Board. The displays can be accessed over two different interfaces:
+The CT Board provides four 7-segment displays. The displays can be accessed through two different interfaces:
   * The [[7segment_bin|binary]] interface, for HEX representation of binary values
-  * The [[7segment_raw|"raw"]] interface, for independent controll over each segment
+  * The [[7segment_raw|"segment control"]] interface, for independent control of each segment
 Depending on the used addresses the display will switch automatically. \\ \\
-===== HEX Display =====
-Additionally the display can be used as HEX display. All 4 displays can directly show a 16 bit binary value. \\
-In this mode the display can't be switched off, use the [[#segment_control|raw interface]]. \\ \\
-==== Programming Example ====
-The code snippet bellow 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. */

-                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.
