EMBC(281) changes the current EM (Extended Data Memory) bank to the
one indicated by the EM bank number (N). At the same time, the new EM
bank number is output to A301.
There are up to 13 banks (0 to C) available in the EM Area and there are
32,768 words (E00000 to E32767) in each bank. EM addresses can be identi-
fied in the two following ways. EMBC(281) must be used to change the current
EM bank if the first method is used.
1. EM addresses can be specified without the bank number, i.e. E00000 to
E32767, to indicate addresses in the current EM bank.
2. EM addresses can be specified with the bank number, i.e. En_00000 to
En_32767 (n = 0 to C), to indicate addresses in a particular EM bank.
