This register can read data in RX FIFO. The size of RX FIFO is
256 byte and it can be accessed by the MCU or by VRXDMA.
RX FIFO Write Pointer: Total is 9-bit with MRFCWP8 in the
MRFCSTS register. It is increased by ’1’ whenever data is written
to the RX FIFO.
RX FIFO Read Pointer: Total is 9-bit with MRFCRP8 in the
MRFCSTS register. It is increased by ‘1’ whenever data is read
from the RX FIFO.
Reserved
When this field is set to ‘1’, it automatically sets the starting address
of a packet and the length of a packet decrypted by the AES engine
to the information of the received packet.
When this field is set to ‘1’, MRXFIFO is enabled.
When this field is set to ‘1’, MRFCWP, MRFCRP, MRFCSTS,
MRFCSIZE, MRFCRM registers are initialized.
Total is 9-bit address with MRFCWP register. This field is the MSB,
and is used to detect wrap around of a circular FIFO.
Total is 9-bit address with MRFCRP register. This field is the MSB,
and is used to detect wrap around of a circular FIFO.
Reserved
Set to ‘1’ when data size in the RX FIFO is 256 byte.
Set to ‘1’ when data size in the RX FIFO is ‘0’.
Represents the number of valid data bytes in the RX FIFO. This
field value is valid when the FIFO status is normal and is calculated
by the difference between MRFCWP and MRFCRP.
Represents the starting address of the data to be decrypted by the
AES engine in the RX FIFO. This field is set by the MCU or is set
automatically to the starting address of the received packet when
the ASA field in the MRFCCTL register is set to ‘1’.
Represents the length of the data to be decrypted by the AES
engine in the RX FIFO. This field is set by the MCU or is set
automatically to the length of the received packet when the ASA
field in the MRFCCTL register is set to ‘1’.
