D
0x00 R Amount of data present in Rx FIFO
RFRXFTHRS (0x61C9) – Rx FIFO Threshold
Bit

RFRXFWR (0x61CA) – Rx FIFO Write Register
Bit
Name Reset R/W Description
No.
7:0
D
0x00 W Data written to this register is written to the Rx FIFO address at offset
RFRXFWP from the start of the Rx FIFO area (see Figure 25-1).
RFRXFWP (and RFRXFSWP if RFFCFG.RXAUTODEALLOC = 1) is
incremented by 1 modulo 0x80 unless the write fails.
