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.
#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. */
.equ ADDR_DIPSW, 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.
