DETAILS
IRQ0RXS<1:0>: IRQ0 Receive Stand-by bits
These bits control the IRQ0 source in Receive and Stand-by modes:
If DMODE1:DMODE0 = 00
11 = SYNC
10 = SYNC
01 = RSSI
00 = Sync (default)
If DMODE1:DMODE0 = 01
11 = SYNC
10 = FIFOEMPTY
01 = WRITEBYTE
00 = - (default)
If DMODE1:DMODE0 = 1x
11 = SYNC or ARDSMATCH
10 = FIFOEMPTY
01 = WRITEBYTE
00 = PLREADY
IRQ1RXS<1:0>: IRQ1 Receive Stand-by bits
These bits control the IRQ1 source in Receive and Stand-by modes:
If DMODE1:DMODE0 = 00
xx = DCLK
If DMODE1:DMODE0 = 01
11 = FIFO_THRESHOLD
10 = RSSI
01 = FIFOFULL
00 = - (default)
If DMODE1:DMODE0 = 1x
11 = FIFO_THRESHOLD
10 = RSSI
01 = FIFOFULL
00 = CRCOK (default)
