10.2.5.52 ATPL360_REG_THRESHOLDS_TABLE_VLO (0x4029)

Table of thresholds to automatically update Tx Mode (see ATPL360_REG_CFG_IMPEDANCE (0x401F)) from VERY_LOW mode. These parameters are only used if ATMC is enabled (see ATPL360_REG_CFG_AUTODETECT_IMPEDANCE (0x401E)).

Corrected RMS_CALC (see ATPL360_REG_CORRECTED_RMS_CALC (0x4033)) is compared with these thresholds after every transmission to select Tx Mode for next transmission. The decision is taken following the steps shown below:

If corrected RMS_CALC is below TH_VLO_VLO_x, Tx Mode will remain in VERY_LOW mode
Else if corrected RMS_CALC is above TH_VLO_HI_x, Tx Mode will be updated to HIGH mode
Else Tx Mode will be updated to LOW mode

where:

TH_VLO_VLO_x: Threshold to remain Tx mode in VERY_LOW mode for Tx attenuation level x (3 dB steps)
TH_VLO_HI_x: Threshold to change from VERY_LOW to HIGH mode for Tx attenuation level x (3 dB steps)

Access: Read-write.

Value Range: 64 bytes (see Table 10-9).

Default Value: See Table 10-10.
