HMS81004E/08E/16E/24E/32E
Y indexed direct page (8 bit offset)
This address value is the second byte (Operand) of com-
mand plus the data of Y-register, which assigns Memory in
Direct page.
This is same with above (2). Use Y register instead of X.
Y indexed absolute
Sets the value of 16-bit absolute address plus Y-register
data as Memory. This addressing mode can specify mem-
ory in whole area.
Example; Y=55
D500FA
(6) Indirect Addressing
Direct page indirect
Assigns data address to use for accomplishing command
which sets memory data(or pair memory) by Operand.
Also index can be used with Index register X,Y.
