Interrupt when the WUC has timed out
Interrupt when the SPI is ready for access
Asserted when a packet has finished transmitting (packet mode only)
Asserted when the WUC has timed out
Asserted when the SPI is ready for access
Description
Interrupt when the battery voltage has dropped below the threshold
value (BATTERY_MONITOR_THRESHOLD_VOLTAGE, Address 0x32D)
1: interrupt enabled; 0: interrupt disabled
Interrupt when the communications processor is ready to load a new
command; mirrors the CMD_READY bit of the status word
1: interrupt enabled; 0: interrupt disabled
1: interrupt enabled; 0: interrupt disabled
1: interrupt enabled; 0: interrupt disabled
Interrupt when the communications processor has finished
performing a command
1: interrupt enabled; 0: interrupt disabled
Interrupt Description
Asserted when the number of WUC wake-ups
(NUMBER_OF_WAKEUPS[15:0]) has reached the threshold
(NUMBER_OF_WAKEUPS_IRQ_THRESHOLD[15:0])
Asserted when the measured RSSI during smart wake mode has
exceeded the RSSI threshold value (SWM_RSSI_THRESH,
Address 0x108)
Asserted when an AES encryption or decryption command is
complete; available only when the AES firmware module has been
loaded to the ADF7023-J program RAM
Asserted when a received packet has a valid address match (packet
mode only)
Asserted when a received packet has the correct CRC (packet mode only)
Asserted when a qualified sync word has been detected in the
received packet
Asserted when a qualified preamble has been detected in the
received packet
Asserted when the battery voltage has dropped below the threshold
value (BATTERY_MONITOR_THRESHOLD_VOLTAGE, Address 0x32D)
Asserted when the communications processor is ready to load a new
command; mirrors the CMD_READY bit of the status word
Asserted when the communications processor has finished
performing a command
