properly, which can be done through API command. The feedback information can be configured into 2 modes, the peak detect mode
and peak and power detect mode. In peak detect mode, the over-range and under-range conditions of both APD and HB detectors will
be provided through DGPIO pins to user. In peak and power detect mode, over-range and under-range conditions of power detector,
over-range and under-range condition of APD will be provided through DGPIO pins to user.
Table 55 describes feedback configuration and the bitfield definition and position. For example, when it is configured in peak mode, the
user could connect to a set of DGPIO pins to retrieve all the APD and HB detector status. Note the DGPIO pins could be selected from
pin 0 to pin 15 and 2 consecutive DGPIO pins should always be configured as a pair to retrieve 2 consecutive bitfields (bit 0&1 or bit 2&3
in both modes). DGPIO pin selection is defined by the following enum type:
typedef enum adi_adrv9001_GpioPinCrumbSel
{
ADI_ADRV9001_GPIO_PIN_CRUMB_UNASSIGNED,
ADI_ADRV9001_GPIO_PIN_CRUMB_01_00,
ADI_ADRV9001_GPIO_PIN_CRUMB_03_02,
ADI_ADRV9001_GPIO_PIN_CRUMB_05_04,
ADI_ADRV9001_GPIO_PIN_CRUMB_07_06,
ADI_ADRV9001_GPIO_PIN_CRUMB_09_08,
ADI_ADRV9001_GPIO_PIN_CRUMB_11_10,
ADI_ADRV9001_GPIO_PIN_CRUMB_13_12,
ADI_ADRV9001_GPIO_PIN_CRUMB_15_14,
} adi_adrv9001_GpioPinCrumbSel_e
In both peak mode and peak and power mode, a pair of bits (bit 0&1 or bit 2&3) can choose any one pair of GPIO pins defined in
"adi_adrv9001_GpioPinCrumbSel_e". If "ADI_ADRV9001_GPIO_PIN_CRUMB_UNASSIGNED" is selected, it means no GPIO pins
assigned so the corresponding bitfields cannot be observed by user. The DGPIO pins can be associated with either one of the receivers
Rx1 or Rx2.
