Description
Version number. Current version is 2.
The device part number. The EM2420 has part number 0x002.
Description
The time in 5 us steps between the time the RX chain is enabled
and the demodulator and AGC is enabled. The RX chain is
started when the bandpass filter has been calibrated (after 6.5
symbol periods).
The time in advance the RXTX switch is set high, before
enabling TX. In µs.
The time in advance the PA is powered up before enabling TX.
In µs.
The time after the last chip in the packet is sent, and the rxtx
switch is disabled. In µs.
The time after the last chip in the packet is sent, and the PA is
set in power-down. Also the time at which the modulator is
disabled. In µs.
