Address to write the upper word
Lower word of write data (16 bits)
Upper word of write data (16 bits)
Lowest address of the block (note that this should be an even address).
(i.e. H'0000 0000 for block 0, H'0001 0000 for block 1)
A desired even address in the user ROM, data flash, or user boot ROM.
Lower eight bits of command code (ignored)
