REGISTER NAME
INT_STATUS
MODEM_REQUEST
DESCRIPTION
b[0] = 0 --> indicates the pck_tx_ready interrupt occurred
b[1] = 0 --> indicates the pck_received interrupt occurred
b[2] = 0 --> indicates the cca_ed_ready interrupt occurred
b[3] = 0 --> indicates the plme_ready interrupt occurred
b[7:4] not used
Via this register, the modem interrupt status can be read. Once
read, the content of the register will automatically set to 0x00.
b[4:0] = 00xxx --> no request (x indicates “don’t care”)
b[4:0] = 01000 --> plme-set-trx-state = FORCE_TRX_OFF
b[4:0] = 01010 --> plme-set-trx-state = RX_ON
b[4:0] = 01011 --> plme-set-trx-state = TX_ON
b[4:0] = 01100 --> pd-data.request (TX-data)
b[4:0] = 01101 --> plme-ED.request
b[4:0] = 01110 --> plme-CCA.request
b[4:0] = 01111 --> not used
b[4:0] = 10000 --> PLL off
b[4:0] = 10001 --> PLL on
b[6:5] = 00 --> not used
b[6:5] = 01 --> CCA mode1
b[6:5] = 10 --> CCA mode2
b[6:5] = 11 --> CCA mode3
b[7] = 0 --> after full reception of a packet, the modem is accepting
new incoming data (continuous packet reception)
b[7] = 0 --> after full reception of a packet, the PLME goes to
TRX_OFF state (one shot packet reception)
This register is used for:
1. Sending PLME related requests to the modem.
2. Defining CCA mode for clear channel assessment .
3. Defining whether the modem should be sensitive for data after
a full reception of a data packet.
