PHYSTS0 (PHY STATUS0 REGISTER, 0x2270)
These registers are used to monitor or control the state of the modulation or demodulation blocks in the
modem block.

RX Status Lock-up: Fixes the state of the demodulation block to a
defined state. With a desired state in the RXSTS field, setting ‘0’ in the
RXSTSF field, caused the state of the demodulation block to be fixed
and retained until RXSTSF is set to ‘1’.
RX Block Status: Shows the state of the demodulation block in a
modem block. RXSTS field can read the current state of the
demodulation block. This field stores the state to be changed.
However, the state of the demodulation block is not changed as a new
state is only recorded to this field. In order to be changed to the recorded
state, RXSTSF field should be set to ‘0’. The state in RXSTS field can
be different from the recorded state because RXSTS shows the current
state of demodulation block which is updated from the recorded state.
The following table shows the state in RXSTS.
TX Block Status. This field shows the state of the modulation block in
the modem block. TXSTS field can read the current state of the
modulation block. This field stores the state to be changed. However,
the state of the modulation block is not changed as a new state is only
recorded to this field. In order to be changed to the recorded state,
TXSTSF field should be set to ‘0’. The state in TXSTS field can be
different from the recorded state because TXSTS shows the current
state of modulation block. The following table shows the state in
TXSTS.
RXSTS=’000’
RXSTS=’001’
RXSTS=’010’
RXSTS=’011’
RXSTS=’100’
RXSTS=’101’
RXSTS=’110’
RXSTS=’111’
Equation 5 – Definition of Single-Tone Frequency
RX_IDLE: The demodulation block cannot receive a
packet.
RX_PKTD: The demodulation block is waiting for
reception of a packet (RX ready state).
RX_WAIT: The demodulation block is waiting for the
completion of the timing synchronization following
packet detection.
RX_CFE1: Coarse carrier frequency offset The
demodulation block is in the first stage of coarse carrier
frequency offset estimation (CFE) waiting for a receive
signal adequate for CFE.
RX_CFE2: The demodulation block is in the second
stage of CFE estimating the coarse offset of the carrier
frequency.
RX_SYMD1: The demodulation block is in the first
stage of symbol detection (SYMD) waiting for a receive
signal adequate for SYMD.
RX_SYMD2: The demodulation block is in the second
stage of the SYMD detecting the symbol from the
received signal.
RX_PKTEND: The demodulation block ends a
successful packet reception.
