Description
Data Memory (EM) (banks 0 to 18) as one series of addresses. If the contents of an address
with the @ symbol exceeds 32767, the address will be assumed to be an address in the
Extended Data Memory (EM) continuing on from 0 in bank No. 0.
Example: If the Data Memory (DM) word contains 32768, E0_0 in bank 0 in Extended Data
Memory (EM) would be specified. If the Extended Data Memory (EM) bank number is speci-
fied as "n" and the contents of the word exceeds 32767, the address will be assumed to be
an address in the Extended Data Memory (EM) continuing on from 0 in bank N+1.
Example: If bank 2 in Extended Data Memory (EM) contains 32768, E3_0 in bank number 3
in Extended Data Memory (EM) would be specified.
