VMCU_SFR - Milo-D/libvmcu-Virtual-MCU-Library GitHub Wiki

Definition

Defined in libvmcu_analyzer.h
`typedef enum { ..., VMCU_SFR_UBRR0H, ... } VMCU_SFR;`

Description

Enumeration of AVR special function registers (SFRs). For example, VMCU_SFR_EECR = EECR (eeprom control register).

Example

#include "libvmcu_analyzer.h" // VMCU_SFR

int main(const int argc, const char **argv) {
   
    vmcu_model_t *m328p = vmcu_model_ctor(VMCU_DEVICE_M328P);
    vmcu_report_t *report = vmcu_analyze_file("file.hex", m328p);

    for(uint32_t i = 0; i < report->n_sfr; i++) {

        vmcu_sfr_t *sfr = &report->sfr[i];

        if(sfr->id == VMCU_TIFR0)
            printf("TIFR0 is being used in file.hex\n");
    }   

    vmcu_report_dtor(report);
    vmcu_model_dtor(m328p);

    return 0;
}

Possible Output

TIFR0 is being used in file.hex

Notes

1 The integer value of a single VMCU_SFR does not have a special meaning
2 VMCU_SFR_NONE = -1 (no SFR)
3 VMCU_SFR will be extended once libvmcu is supporting other devices than the ATmega328(P)
