access, then 72-bits of data must be loaded to the internal
memory buffer per memory address. This is accomplished
by performing three (3) 24-bit master to slave loads. Table 9
demonstrates the sequence of writes necessary to load
memory location 0 of the I and Q channel coefficient RAMs
simultaneously.
If auto-increment address mode had been enabled, then the
write to MasterReg<31:24> with the destination memory
address would not have been required, as writing to Control
Word 0 would reset the internal auto-increment address to 0.
Writing a 0x0F to address 4 generates an internal
memUpdate signal that loads the memory buffer from
MasterReg<23:0>. Which section of the memory buffer gets
the data is dependent on the memory word select counter
shown in column 7 of Table 9. A memUpdate strobe
increments the word select counter as well as updating the
memBuffer. When the word select counter is equal to 2 and
a memUpdate strobe occurs, memBuf<71:0> data is written
to memAddr<7:0> of the I/Q coefficient RAMs and the mem
word select counter is cleared ready for the next sequence of
writes to the memory buffer. Writing to the constellation map
RAM is much simpler as Table 10 demonstrates.
