Addressing Modes
RAM Addressing Modes
Register Indirect Addressing Mode:
The contents of the W, X, and Y registers (10 bits total) are used as
a RAM address.
Direct Addressing Mode:
A direct addressing instruction consists of two words. The first word contains
the opcode, and the contents of the second word (10 bits) are used as a RAM address.
Memory Register Addressing Mode (LAMR, XMRA):
The memory registers (MR), which are located
in 16 addresses from $040 to $04F, are accessed with the LAMR and XMRA instructions.
