Command Sequence:
Operand Data:
None
Result Data:
Requested data is returned as either a word or longword. Byte data is returned in the least significant byte
of a word result. Word results return 16 bits of significant data; longword results return 32 bits. A value of
$0001 (with the status bit set) is returned if a bus error occurs.
20.3.4.1.6
FILL is used in conjunction with the WRITE command to access large blocks of memory. An initial
WRITE is executed to set up the starting address of the block and to supply the first operand. The FILL
command writes subsequent operands. The initial address is incremented by the operand size (1, 2, or 4)
and saved in a temporary register after the memory write. Subsequent FILL commands use this address,
perform the write, increment it by the current operand size, and store the updated address in the temporary
register.

Fill Memory Block (FILL)
The FILL command does not check for a valid address FILL is a valid
command only when preceded by another FILL, NOP or by a WRITE
command. Otherwise, an illegal command response is returned. The NOP
command can be used for intercommand padding without corrupting the
address pointer.
