The Smart Fuse Configurator comes with a C header file that was generated from the register map of each supported high-side switch. Initially, this includes the TPS2HCS10-Q1 device. The header files are available on the product page and includes functionality such as:

• C structure for each bitfield/enumeration of each register
• Mask definitions of each bitfield
• Offset definitions of each bitfield
• Enumerations of each bitfield

This header file is meant to be used to enable software development on an embedded C platform. An excerpt of the SW_STATE register can be seen below.

/* --------- TPS2HC10S_SW_STATE (0x07) ----------*/
/* DESCRIPTION:  */

#define TPS2HC10S_SW_STATE_REG 0x07

typedef union 
{
    uint16_t bytes;
    struct
    {
        /* Set this bit to 1 to turn on the FET and CH1 output ON */
        unsigned CH1_ON : 1;
        /* Set this bit to 1 to turn on the FET and CH2 output ON */
        unsigned CH2_ON : 1;
        /* Reserved */
        unsigned RESERVED_14 : 14;
    } bits;
} TPS2HC10S_SW_STATE;

#define TPS2HC10S_SW_STATE_CH1_ON_MASK 0x01
#define TPS2HC10S_SW_STATE_CH1_ON_OFS 0

typedef enum {
    ch1_on_en_1_0x1 = 0x1,
    ch1_on_en_2_0x3 = 0x3,
} ch1_on_t;

#define TPS2HC10S_SW_STATE_CH2_ON_MASK 0x02
#define TPS2HC10S_SW_STATE_CH2_ON_OFS 1

typedef enum {
    ch2_on_en_1_0x1 = 0x2,
    ch2_on_en_2_0x2 = 0x4,
} ch2_on_t;

An example of using the bit-wise operation to set CH1 to enabled can be seen below.

int main()
{
    TPS2HC10S_SW_STATE enableReg;
    
    enableReg.bits.CH1_ON = 1;

    printf("\nChannel Enable: 0x%x\n", enableReg.byte);

    return 0;
}

A byte-wise example can be seen below.

#include "tps2hcs10.h"
#include <stdio.h>

int main()
{
    TPS2HC10S_SW_STATE enableReg;
    
    enableReg.byte = 0x01;

    printf("\nChannel Enable: 0x%x\n", enableReg.byte);

    return 0;
}
