Valid Lora signal detected during CAD operation: a write
operation clears IRQ
n/a Number of payload bytes of latest packet received
Number of valid headers received since last transition into Rx
n/a mode, MSB(15:8). Header and packet counters are reseted in
Sleep mode.
Number of valid headers received since last transition into Rx
n/a mode, LSB(7:0). Header and packet counters are reseted in
Sleep mode.
Number of valid packets received since last transition into Rx
n/a mode, MSB(15:8). Header and packet counters are reseted in
Sleep mode.
Number of valid packets received since last transition into Rx
n/a mode, LSB(7:0). Header and packet counters are reseted in
Sleep mode.
