Description
Battery voltage dropped below the user-set threshold value
Communications processor ready to accept a new command
Wake-up timer has timed out
SPI ready for access
Command has finished
Description
ADC readback of LSBs
Description
The battery monitor threshold voltage sets the alarm level for the battery
monitor. The alarm is raised by the interrupt. Battery monitor trip voltage,
V
Description
Optional output clock frequency on XOSC32KP_GP5_ATB1.
Output frequency = XTAL/EXT_UC_CLK_DIVIDE. To disable,
set EXT_UC_CLK_DIVIDE = 0.
Description
AGC clock divider for 2FSK/GFSK/MSK/GMSK mode. The AGC rate is
(26 MHz/(16 × AGC_CLK_DIVIDE)).
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 packet has finished transmitting (packet mode only)
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
TRIP
= 1.7 V + 62 mV × BATTMON_VOLTAGE.
