Connection interrupt status and Clear register
| CONN_CLOSED | If this bit is set it indicates that the link is disconnected. If this bit is written with 1, it clears the connection updated interrupt. |
| CONN_ESTB | If this bit is set it indicates that the connection has been established. The bit is also set when a connection update procedure is complet-ed, at the start of the first anchor point with the updated parameters. If this bit is written with 1, it clears the connection established interrupt. |
| MAP_UPDT_DONE | If this bit is set it indicates that the channel map update is completed at the instant specified by the firmware. If this bit is written with 1, it clears the map update done interrupt. |
| START_CE | If this bit is set it indicates that the connection event started interrupt has happened. If this bit is written with 1, it clears the connection event started interrupt. |
| CLOSE_CE | If this bit is set it indicates that the connection event closed interrupt has happened. If this bit is written with 1, it clears the connection event closed interrupt. |
| CE_TX_ACK | If this bit is set it indicates that the connection event transmission acknowledgement is received for the previous non-empty packet transmitted. If this bit is written with 1, it clears the ce transmission acknowledgement interrupt. |
| CE_RX | If this bit is set it indicates that a packet is received in the connection event. If this bit is written with 1, it clears the connection event received interrupt. |
| CON_UPDT_DONE | This bit is set when the last connection event with previous connec-tion parameters is reached. The bit is set immediately after the re-ceive operation at the anchor point of the last connection event. If this bit is written with 1, it clears the connection updated interrupt. |
| DISCON_STATUS | Reason for disconnect - indicates the reason the link is disconnected by hardware. 001 - connection failed to be established 010 - supervision timeout 011 - kill connection by host 100 - kill connection after ACK transmitted 101 - PDU response timer expired |
| RX_PDU_STATUS | Status of PDU received. This information is valid along with receive interrupt. xx1 - Bad Packet (packet with CRC error) 000 - empty PDU 010 - new data (non-empty) PDU 110 - Duplicate Packet |
| PING_TIMER_EXPIRD_INTR | If this is set, it indicates that ping timer has expired. If this bit is written with 1, it clears the interrupt. |
| PING_NEARLY_EXPIRD_INTR | If this is set, it indicates that ping timer has nearly expired. If this bit is written with 1, it clears the interrupt. |
