111111111 (1ffh) = block number 511
Bit 14/Indirect Access Read/Write (IARW). When the host wishes to read data from the internal receive block
pointer RAM, the host should write this bit to 1. This causes the device to begin obtaining the data from the block
location indicated by the BLKID bits. During the read access, the IAB bit is set to 1. Once the data is ready to be
read from the RFBP register, the IAB bit is set to 0. When the host wishes to write data to the internal receive
block pointer RAM, this bit should be written to 0 by the host. This causes the device to take the data that is
currently present in the RFBP register and write it to the channel location indicated by the BLKID bits. When the
device has completed the write, the IAB is set to 0.
Bit 15/Indirect Access Busy (IAB). When an indirect read or write access is in progress, this read-only bit is set
to 1. During a read operation, this bit is set to 1 until the data is ready to be read. It is set to 0 when the data is
ready to be read. During a write operation, this bit is set to 1 while the write is taking place. It is set to 0 once the
write operation has completed.

Bits 0 to 8/Block Pointer (RBP0 to RBP8). These bits indicate which of the 512 blocks is the next block in the
link-list chain. A block is not allowed to point to itself.
000000000 (000h) = block 0 is the next linked block
111111111 (1ffh) = block 511 is the next linked block
