Polarity of the output signal FIFO.
0 : Polarity is as described in the specification
1 : Polarity is inverted as compared to the specification
Polarity of the output signal FIFOP.
0 : Polarity is as described in the specification
1 : Polarity is inverted as compared to the specification
Polarity of the SFD pin.
0 : Polarity is as described in the specification
1 : Polarity is inverted as compared to the specification
Polarity of the CCA pin.
FIFOP_THR sets the threshold in number of bytes in the
RXFIFO for FIFOP to go high.
Description
Reserved, write as 0
The HSSD module is used as follows:
0: Off.
1: Output AGC status (gain setting / peak detector status /
accumulator value)
2: Output ADC I and Q values.
3: Output I/Q after digital downmix and channel filtering.
4: Reserved
5: Reserved
6: Input ADC I and Q values
7: Input DAC I and Q values.
The HSSD module requires that the FS is up and running as it
uses CLK_PRE (~150 MHZ) to produce its ~37.5 MHz data clock
and serialize its output words.
Multiplexer setting for the SFD pin.
Multiplexer setting for the CCA pin.
Description
The device part number. The EM2420 has part number 0x002.
Gives the JEDEC manufacturer ID. The actual manufacturer ID
can be found in MANFID[7:1], the number of continuation bytes
in MANFID[11:8] and MANFID[0]=1.
The JEDEC manufacturer ID is 0x7F 0x7F 0x7F 0x9E (0x1E
preceded by three continuation bytes.)
