====== DIPSW ======

The CT Board features 32 DIP switches. They are arranged in 4 groups of 8 DIP switches. \\
If a DIP switch is in the position "high" (see [[#diagram]] below) it provides a logical **"1"**. \\ \\

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

The code snippets below show how to use the DIPSW.

<code c>
#include "reg_ctboard.h"

uint8_t data_byte = CT_DIPSW->BYTE.S7_0;       /* Read byte from S7..0. */
uint16_t data_hword = CT_DIPSW->HWORD.S31_16;  /* Read half word from S31..16. */
uint32_t data_word = CT_DIPSW->WORD;           /* Read all DIPSW at once into a word. */

<code asm>
ADDR_DIPSW      EQU      0x60000200
                
                LDR      r0, =ADDR_DIPSW
                LDRB     r1, [r0, #0]          ; Read byte from S7..0.
                LDRH     r1, [r0, #2]          ; Read half word from S31..16.
                LDR      r1, [r0, #0]          ; Read all DIPSW at once into a word.
