CC25000x1D: AGCCTRL0 – AGC controlBit Field Name Reset R/W Description7:6 HYST_LEVEL[1:0] 2 (10) R/W Sets the level of hysteresis on the magnitude deviation(internal AGC signal that determine gain changes).Setting0 (00)1 (01)2 (10)3 (11)DescriptionNo hysteresis, small symmetric dead zone,high gainLow hysteresis, small asymmetric dead zone,medium gainMedium hysteresis, medium asymmetric deadzone, medium gainLarge hysteresis, large asymmetric deadzone, low gain5:4 WAIT_TIME[1:0] 1 (01) R/W Sets the number of channel filter samples from a gainadjustment has been made until the AGC algorithm startsaccumulating new samples.Setting0 (00) 81 (01) 162 (10) 243 (11) 32Channel filter samples3:2 AGC_FREEZE[1:0] 0 (00) R/W Controls when the AGC gain should be frozen.Setting0 (00)1 (01)2 (10)3 (11)FunctionNormal operation. Always adjust gain whenrequired.The gain setting is frozen when a sync word hasbeen found.Manually freezes the analog gain setting andcontinue to adjust the digital gain.Manually freezes both the analog and the digitalgain settings. Used for manually overriding thegain.1:0 FILTER_LENGTH[1:0] 1 (01) R/W Sets the averaging length for the amplitude from the channelfilter.Setting0 (00) 81 (01) 162 (10) 323 (11) 64Channel filter samples0x1E: WOREVT1 – High byte Event0 timeoutBit Field Name Reset R/W Description7:0 EVENT0[15:8] 135 (0x87) R/W High byte of Event 0 timeout registert750 ⋅5 WOR _ RESEvent0 = ⋅ EVENT0⋅2fXOSCPRELIMINARY Data Sheet (Rev.1.2) SWRS040A Page 71 of 83
