6.3. Interrupt Configuration Parameters - IRQParam
The detailed description of the IRQParam register is given in Table 28.

Description
Configures the size of the FIFO:
00 -> 16 bytes (d)
01 -> 32 bytes
10 -> 48 bytes
11 -> 64 bytes
Number of bytes to be written in the FIFO to activate the
Fifo_threshold interrupts
Actual number of bytes = B + 1, where B is the value in the register.
(d): B = 001111 => Number of bytes = 16
IRQ_0 source in Rx and Standby modes:
Rx_stby_irq_0
7-6 13
If Data_mode(1:0) = 00 (Continuous mode):
00 => Sync (d)
01=> RSSI
10 => Sync
11=> Sync
If Data_mode(1:0) = 01 (Buffered mode):
00 => - (d)
r/w 01=> Write_byte
10=> /Fifoempty*
11 Sync
If Data_mode(1:0) = 1x (Packet mode):
00=> Payload_ready (d)
01 => Write_byte
10=> /Fifoempty*
11 => Sync or Adrs_match (the latter if address filtering is enabled)
*also available in Standby mode (Cf sections 5.4.4 and 5.5.7)
IRQ_1 source in Rx and Standby modes:
Rx_stby_irq_1
5-4 13
If Data_mode(1:0) = 00 (Continuous mode):
xx =>DCLK
If Data_mode(1:0) = 01 (Buffered mode):
00=> - (d)
01=> Fifofull*
r/w
10=> RSSI
11=> Fifo_threshold*
If Data_mode(1:0) = 1x (Packet mode):
00=> CRC_ok (d)
01=> Fifofull*
10 => RSSI
11=> Fifo_threshold*

*also available in Standby mode (Cf sections 5.4.4 and 5.5.7)
Tx start condition and IRQ_0 source:
0 => Start transmission when the number of bytes in FIFO is greater than or
r/w equal to the threshold set by MCParam_Fifo_thresh parameter (Cf section
5.2.2.3), IRQ_0 mapped to Fifo_threshold (d)
1 => Tx starts if FIFO is not empty, IRQ_0 mapped to /Fifoempty
