I'm debugging AFE4400 register read and write functionality. AFE4400 register write as below code;
uint32_t AFE44xx_Default_Register_Settings[49] = {

};
for (i=0; i<49; i++)
{
_afe4400_set_reg(i, AFE44xx_Default_Register_Settings[i]);
}
the LED is turned on; and seems the registers are written correctly. And I tried to read the register value with below code segment;
_afe4400_set_reg(0, 0x000001);
for (i=42; i<44; i++)
{
_afe4400_get_reg(i);
}
The registers can NOT be read out correctly. Anybody shall give me some advices? Thanks in advance!!
