2.10.2 Event Configuration

There are two different types of event flags:

  • System-specific event flags
  • Service-specific event flags

The system-specific event flags can be configured (masked) in the eepEventConf EEPROM variable.

  • The pinEventConf variable contains the configuration masks for the wake-up events (NPWRONx and PWRON). If a wake-up event occurs and the corresponding mask bit is set, the EVENT pin is set by the firmware.
  • The sysEventConf variable contains the configuration masks for the system events (SYS_ERR, SYS_RDY, AVCCLOW and LOWBATT). If a system event occurs and the corresponding mask bit is set, the EVENT pin is set by the firmware.
  • The cmdRdyConf variable contains the masks for the CMD_RDY event flag. If a mask bit is set, the EVENT pin is set after the corresponding operation initializes or completes.
Table 2-11. System-Specific Event Flag Configuration Overview
Address Name Bit 7 Bit 6 Bit 5 Bit 4 Bit 3 Bit 2 Bit 1 Bit 0
0x0094 pinEventConf PWRON — NPWRON6 NPWRON5 NPWRON4 NPWRON3 NPWRON2 NPWRON1
0x0095 sysEventConf SYS_ERR — SYS_RDY AVCCLOW LOWBATT RX_ACTIVE_EN RX_ACTIVE_POL IRQ_POL
0x0096 cmdRdyConf ANT_TUNE TEMP_MEAS SRC_CAL FRC_CAL VCO_CAL RF_CAL SELFCHECK TX

The service-specific event flags can be configured for each service. The configuration bytes are located in the eepServices data structure.

  • rssiSysConf contains the mask and the threshold for the SFIFO event flag during a receive mode. If the rssiBufEvMask mask is set, the EVENT pin is set as soon as the SFIFO is filled with RSSIbuf bytes.
  • rxSetPathA/B[0] contains the masks and the thresholds for the DFIFO_RX event flag. The EVENT pin is set at reception on path A/B if the rxBufEvMaskA/B mask is set and the DFIFO is filled with RxbufA/B bytes.
  • rxSysEvent contains the masks for the RF events for path A/B. If a mask bit is set, the EVENT pin is set after the corresponding event is detected by the firmware.
  • txSysEventA/B contains the masks and the thresholds for the DFIFO_TX event flag. The EVENT pin is set at transmission on path A/B if the txBufEvMaskA/B mask is set and the DFIFO is filled with TxbufA/B bytes.
  • txPreambleSysEventA/B contains the masks for the SFIFO event flag during transmit mode. If the txPreambleBufEvMaskA/B mask is set, the EVENT pin is set if the SFIFO is filled with PreambleBufFillLevelA/B bytes.

The following table shows an overview of the service-specific, event-flag configuration.
