Addressing Capabilities
2.2.4 Address Register Indirect with Postincrement Mode
In the address register indirect with postincrement mode, the operand is in memory. The
effective address field specifies the address register containing the address of the operand
in memory. After the operand address is used, it is incremented by one, two, or four
depending on the size of the operand: byte, word, or long word, respectively. Coprocessors
may support incrementing for any operand size, up to 255 bytes. If the address register is
the stack pointer and the operand size is byte, the address is incremented by two to keep
the stack pointer aligned to a word boundary.
