momiji::operands::AddressIndex
Defined in header <momiji/Parser.h>
struct AddressIndexAn operand of the form (X, Y*, a*) where ‘*’ is any number from 0 to 7,
‘Y’ is any data or address register and ‘X’ is any compile-time expression.
This references the address inside the address register plus the value
inside the register ‘Y*’ plus the value of ‘X’.
It’s also possible to omit ‘X’, which results in an expression of the form
(Y*, a*).
