Operand Data:
Result Data:
5.6.2.8.11 Fill Memory Block (FILL). FILL is used in conjunction with the WRITE com-
mand to fill large blocks of memory. An initial WRITE is executed to set up the starting
address of the block and to supply the first operand. Subsequent operands are written with
the FILL command. The initial address is incremented by the operand size (1, 2, or 4) and
is saved in a temporary register. Subsequent FILL commands use this address, increment
it by the current operand size, and store the updated address back in the temporary register.
The size field is examined each time a FILL command is given, allowing the operand size to
be altered dynamically.

Requested data is returned as either a word or long word. Byte data is returned in the least
significant byte of a word result. Word results return 16 bits of significant data; long-word
results return 32 bits. Status of the read operation is returned as in the READ command:
$0xxxx for success, $10001 for bus or address errors.

The FILL command does not check for a valid address in the
temporary register—FILL is a valid command only when preced-
ed by another FILL or by a WRITE command. Otherwise, the re-
sults are undefined. The NOP command can be used for
intercommand padding without corrupting the address pointer.
