the extension word, and the sized, scaled, and sign-extended index operand.
The value in the PC is the address of the extension word. This reference is
sum of the address in the PC and the sign-extended 16-bit displacement
integer in the extension word. The value in the PC is the address of the
extension word. The reference is a program space reference and is only
allowed for reads (refer to 4.2 ADDRESS SPACE TYPES).

This mode is similar to the address register indirect with index (8-bit dis-
(8-Bit Displacement) Mode, but the PC is used as the base register. The
operand is in memory. The address of the operand is the sum of the address
a program space reference and is only allowed for reads. The user must
include the displacement, the PC, and the index register when specifying this
addressing mode.
In this mode, the operand is in memory. The address of the operand is the
