Description
This function switches the final correction pulse to be applied in the CFR engine in Mode 1 (ADI_ADRV9025_CFR_MODE1)
operation. This function can be used to activate one of the two final correction pulses corresponding to two carrier
configurations when the active carrier configuration is changed during runtime (carrier configuration hot-swapping).
This function can only be executed if 2 correction pulses of length 512(half pulse length of 256) or lesser are programmed into
the device prior to calling this function. If a single correction pulse of length 512 or lesser (half pulse length of 256 or lesser) is
programmed in the device, this function does not have any effect. The correction pulses can be programmed via
adi_adrv9025_CfrCorrectionPulseWrite_v2() API.
Please note that this function does not change the CFR configuration including peak threshold, interpolation factor and CFR
engine enables when the active correction pulse is switched. By default, the device activates
ADI_ADRV9025_CFR_CARRIER_HOT_SWAP_CORR_PULSE_1 on reset. Please note that it is necessary for the CFR engines to be
enabled for the active correction pulse switching to take place. Calling this function when the CFR engines are disabled has no
effect.
Precondition
This runtime function may be called any time after device initialization and two correction pulses of length 512 or lesser(half
pulse length of 256 or lesser) are programmed via adi_adrv9025_CfrCorrectionPulseWrite_v2() API and the CFR init cal has been
executed. The CFR init cal can be executed via adi_adrv9025_InitCalsRun()API. It is also necessary that the mode of operation is
set to ADI_ADRV9025_CFR_MODE1 via adi_adrv9025_CfrCtrlConfigSet() API. It is also necessary that at the time of calling this
function, the CFR engine is required to be enabled; otherwise the active correction pulse switching will not occur.
