Link Layer additional configuration
| RSSI_SEL | Controls the RSSI reads. When this bit is 1, the bit RSSI_INTR_SEL is don’t care. 0 - RSSI read is initiated after the the packet is received 1 - RSSI read is completed before the packet is received. When RCB Interface is operating 4Mhz are lower this bit should be set to 1’b0. |
| TX_RX_CTRL_SEL | Controls the mode of issueing TX_EN & RX_EN to the Radio 1 - TX_EN and RX_EN are issued through direct pins 0 - TX_EN and RX_EN are issued through RCB writes |
| TIFS_ENABLE | Setting this bit enables the tx 1MHz pulse to match the received bpktctl from CYBLERD55. This will result is reduced TIFS variation |
| TIMER_LF_SLOT_ENABLE | Controls the wakeup timer configuration 1 - Wakeup time is compensated with the LF_OFFSET 0 - Wakeup time is not compensated with the LF_OFFSET as in legacy mode |
| RSSI_INTR_SEL | Controls the engine interrupt generation based on RSSI reads. This is valid only if RSSI_SEL is 0. 0 - Receive interrupts are triggerred after the RSSI read is complete 1 - Receive interrupts are triggerred after the last bit of CRC |
| RSSI_EARLY_CNFG | Controls the early RSSI reads. This is applicable only when RSSI_SEL is 1. 1 - RSSI read is initiated during the first CRC byte reception. 0 - RSSI read is initiated during the third CRC byte reception. |
| TX_RX_PIN_DLY | Controls the delay from DBUS_TX, DBUS_RX assertion to the assertion on the pins. This is applicable only when TX_RX_CTRL_SEL is set. 0 - The pin assertion is delayed by 4 cycles. 1 - The pin assertion is delayed by 8 cycles. |
| TX_PA_PWR_LVL_TYPE | Controls the TX power level format given to the CYBLERD55 chip. 0 - The power level given to CYBLERD55 is in 4 bit code format from ADV_CH_TX_POWER for advertising channel and DTM packets & from CONN_CH_TX_POWER for connection channel packets. The power level setting is decoded and given to the PA. 1 - The power level given to CYBLERD55 is in 18 bit power level setting format from {ADV_CH_TX_POWER_LVL_MS, ADV_CH_TX_POWER_LVL_LS} channel and DTM packets & from {CONN_CH_TX_POWER_LVL_MS, CONN_CH_TX_POWER_LVL_LS} for connection channel packets. This setting is directly given to the PA. |
| RSSI_ENERGY_RD | Controls the RSSI reads. 0 - Channel Energy read is not initiated if no packet is received during a receive cycle 1 - Channel Energy read is initiated at the end of the receive cycle if no packet is received |
| RSSI_EACH_PKT | Controls the RSSI reads. 0 - RSSI read is not initiated for zero length and aborted packets 1 - RSSI read is initiated for zero length and aborted packets |
| FORCE_TRIG_RCB_UPDATE | Controls the RCB update to radio on TX/RX enable. Applicable only when TX_RX_CTRL_SEL is 1’b1 0 - RCB update is triggerred only when the fields change on rising edge of TX/RX enable 1 - RCB update is force triggerred on rising edge of TX/RX enable If TX_RX_CTRL_SEL is 1’b1 and ENABLE_RADIO_BOD is 1’b1, this bit needs to be set to 1’b1 |
| CHECK_DUP_CONN | Controls the duplicate connection checkin ADV and INIT 0 - Does not check if the peer is already connection before a new connection is created 1 - Checks if the peer is already connection before a new connection is created and aborts a duplicate connection creation |
| MULTI_ENGINE_LPM | Controls the LPM entry condition 0 - Legacy mode LPM entry check 1 - MMMS mode LPM entry check |
| ADV_DIR_DEVICE_PRIV_EN | Controls the ADV behavior while advertising ADV_DIR and only device privacy is set. When the ADV is transmitting INITA RPA, the bahavior when an Identity address in received from the Initiator in the CONN_REQ is given below 0 - Abort the CONN_REQ and continue with advertisement 1 - Check the address against PEER_SEC_ADDR_ADV and create connection on a match. |
