CSTH<2:0>: Carrier Sense Threshold bits
100 = IEEE 802.15.4™ (250 kbps) optimized value (default)
010 = Turbo mode (625 kbps) optimized value
PRECNT<2:0>: Preamble Counter Threshold bits
111 = Optimized value (default)
Reserved: Maintain as ‘0’
RSSIMODE1: RSSI Mode 1 bit
1 = Initiate RSSI calculation (bit is automatically cleared to ‘0’ by hardware)
RSSIMODE2: RSSI Mode 2 bit
1 = Calculate RSSI for each received packet. The RSSI value is stored in RXFIFO
0 = RSSI calculation is not performed for each received packet (default)
Reserved: Maintain as ‘0’
RSSIRDY: RSSI Ready Signal for RSSIMODE1 bit
If RSSIMODE1 = 1, then
1 = RSSI calculation has finished and the RSSI value is ready
0 = RSSI calculation in progress
