Description
Sets center frequency together with HFREQ_PLL (default value = 001101100_b = 108_d).
f_RF = ( 422.4 + CH_NO_d /10)*(1+HFREQ_PLL_d) MHz
Sets PLL in 433 or 868/915 MHz mode (default value = 0).
'0' – Chip operating in 433MHz band
'1' – Chip operating in 868 or 915 MHz band
Output power (default value = 00).
'00' -10dBm
'01' -2dBm
'10' +6dBm
'11' +10dBm
Reduces current in RX mode by 1.6mA. Sensitivity is reduced (default value = 0).
'0' – Normal operation
'1' – Reduced power
Retransmit contents in TX – register as long TRX_CE and TXEN is high (default value = 0).
'0' – No retransmission
'1' – Retransmission of data package
RX-address width (default value = 100).
'001' – 1 byte RX address field width
.
'100' – 4 byte RX address field width
TX-address width (default value = 100).
'001' – 1 byte TX address field width
.
'100' – 4 byte TX address field width
RX-payload width (default value = 100000).
'000001' – 1 byte RX payload field width
'000010' – 2 byte RX payload field width
.
'100000' – 32 byte RX payload field width
TX-payload width (default value = 100000).
'000001' – 1 byte TX payload field width
'000010' – 2 byte TX payload field width
.
'100000' – 32 byte TX payload field width
RX address identity. Used bytes depend on RX_AFW (default value = E7E7E7E7_h).
CPU clock frequency (default value = 11).
'00' – 4MHz
'01' – 2MHz
'10' – 1MHz
'11' – 500kHz
CPU clock enable (default value = 1).
'0' – CPU using UP_CLK_FREQ frequency
'1' – CPU using XOF frequency
Crystal oscillator frequency. Must be set according to external crystal resonant-frequency.
'000' – 4MHz
(default value = 100)
'001' – 8MHz
'010' – 12MHz
'011' – 16MHz
'100' – 20MHz
CRC – check enable (default value = 1).
'0' – Disable
'1' – Enable
CRC – mode (default value = 1).
'0' – 8 CRC check bit
'1' – 16 CRC check bit
