Trim RSSI Gain
Trim RSSI Offset, enable RSSI pin
LIMGAIN: Trim the RSSI Gain (Slope)
Min: 00h = Minimum gain
Max: 1Fh = Maximum gain
IAF TDA523x Config Tool sets this value to 00h by default
RSSIMTR: Select signal for RSSI pin
00b: RSSI+
01b: RSSI- (reference)
10b: REF+ (reference)
11b: REF- (reference)
RSSIMONE: Enable buffer for RSSI pin
0: buffer off
1: buffer on
LIMOFFS: Trim the RSSI Offset
Min: 0h = Minimum offset
Max: Fh= Maximum offset
IAF TDA523x Config Tool sets this value to 0h by default
AAFILT: Anti Aliasing Filter
00b: 40 kHz use for data rates >9.6 kb/s
01b: 13.6 kHz use for data rates >3 kb/s
10b: 5 kHz use for data rates >2 kb/s
11b: 3.6 kHz use for data rates <=2 kb/s
The anti aliasing filter corner frequency can be changed to achieve better
performance. Note that the corner frequency and the data rate must be set
together.
This value is automatically created by the IAF TDA523x Config Tool
