Note 1: No transfer over the bank is possible. Even when the address is incremented at the breakpoint of the bank and the

source/destination addresses go over the bank, the source address bank select/destination address bank select bits are

not incremented, and the bank head corresponds to the source address/destination address.

Note 2: Because Bank1 does not exist in the 32185, setting Bank1 (A14=0, A15=1) is prohibited.
