Modem Status Page
TRANSMIT READY (TX_RDY) CR7<7:7>
This status bit indicates the status of the TX_RDY output pin.
It is only used when the Preamble/Header is generated
internally within the HSP3824.
ANTENNA CR7<6:6>
This status bit indicates the antenna selected by the device
(status of the ANTSEL pin).
CLEAR CHANNEL ASSESSMENT (CCA) CR7<5:5>
This status bit indicates the status of the Clear Channel
Assessment output pin.
CARRIER SENSE (CRS) CR7<4:4>
This status bit indicates the status of Carrier Sense (or PN
lock).
RSSI VS THRESHOLD CR7<3:3>
This status bit indicates whether the RSSI signal is above or
below threshold (or energy detect (ED)).
MAC DATA READY (MD_RDY) CR7<2:2>
This status bit indicates the status of the MD_RDY output
pin. It signals that a valid Preamble/Header has been
received and that the next available bit on the RXD bus will
be the first data packet bit.
TRANSMIT POWER ENABLE (TX_PE) CR7<1:1>
This status bit indicates whether the external device has
acknowledged that the channel is clear for transmission (or
status of the TX_PE pin).
VALID CRC16 CR7<0:0>
This status bit indicates whether a valid CRC16 has been
calculated for the Header information. The CRC16 does not
cover the preamble bits.
PACKET STATUS CR8<7:7>
This status bit indicates whether a valid packet has been
received. This is meaningful only when the device operates
under the full protocol mode.
START FRAME DELIMITER SEARCH TIMER CR8<6:6>
This status bit indicates the status of the SFD search timer.
MODULATION TYPE CR8<5:5>
This status bit indicates the modulation type for the data
packet. Preamble and Header data are always DBPSK, but
the data can be either DBPSK or DQPSK.
