D0 to D32767 are specified if
@D@@@@@ contains 0000 to 7FFF
hex (0 to 32767 decimal).
E0 _0 to E0 _32767 of bank 0 in the EM
Area are specified if @D@@@@@ con-
tains 8000 to FFFF hex (32768 to
65535 decimal).
E@_0 to E@_32767 in the specified
bank are specified if @E@_@@@@@
contains 0000 to 7FFF hex (0 to 32767
decimal).
E(@+1)_0 to E(@+1)_32767 in the bank
following the specified bank @ are
specified if @E@_@@@@@ contains

Description
@D@@@@@
00000 to 32767
(0000 Hex to
7FFF Hex in BIN)
D
(banks 0 to 18 hex) as one series of addresses. If the contents of an address with the @ sym-
bol exceeds 32767, the address will be assumed to be an address in the EM Area continuing
on from 0 in bank 0.
Example: If the DM Area word contains 32768, E0_0 in bank 0 in the EM Area would be
specified.
If the EM Area bank number is specified as "n" and the contents of the word exceeds 32767,
the address will be assumed to be an address in the EM Area continuing on from 0 in bank
n+1.
Example: If bank 2 in the EM Area contains 32768, E3_0 in bank 3 in the EM Area would be
specified.
