7.2.1 State Control
8321A–MCU Wireless–10/11
The Extended Operating Mode states RX_AACK and TX_ARET are controlled via
register bits TRX_CMD (register 0x02, TRX_STATE), which receives the state
transition commands. The states are usually entered from TRX_OFF or PLL_ON state
as illustrated by
always be confirmed by reading the register bits TRX_STATUS (register 0x01,
TRX_STATUS).
RX_AACK - Receive with Automatic ACK
A state transition to RX_AACK_ON is initiated by writing the command RX_AACK_ON
to the register bits TRX_CMD. The state change should be confirmed by reading
register bits TRX_STATUS (register 0x01, TRX_STATUS).
The RX_AACK state is left by writing a new command to the register bits TRX_CMD. If
the Atmel AT86RF232 is within a frame receive or acknowledgment procedure
(BUSY_RX_AACK), the state change is executed after finishing. Alternatively, the
commands FORCE_TRX_OFF or FORCE_PLL_ON can be used to cancel the
RX_AACK transaction and change into radio transceiver state TRX_OFF or PLL_ON,
respectively.
TX_ARET - Transmit with Automatic Frame Retransmission and CSMA-CA Retry
A state transition to TX_ARET_ON is initiated by writing command TX_ARET_ON to
register bits TRX_CMD. The radio transceiver is in the TX_ARET_ON state after
register bits TRX_STATUS (register 0x01, TRX_STATUS) changes to TX_ARET_ON.
The TX_ARET transaction is started with a rising edge of pin 11 (SLP_TR) or writing
the command TX_START to register bits TRX_CMD.
The TX_ARET state is left by writing a new command to the register bits TRX_CMD. If
the AT86RF232 is within a CSMA-CA transaction, a frame transmission or an
acknowledgment procedure (BUSY_TX_ARET), the state change is executed after
finishing. Alternatively, the command FORCE_TRX_OFF or FORCE_PLL_ON can be
used to instantly terminate the TX_ARET transaction and change into radio transceiver
state TRX_OFF or PLL_ON, respectively.
Note:
1.
A state change request from TRX_OFF to RX_AACK_ON or TX_ARET_ON
internally passes the state PLL_ON. Thus the ability to receive or transmit data
is delayed accordingly. It is recommended to use interrupt IRQ_0 (PLL_LOCK)
as an indicator.
