Signed 7-bit integer data (data is put in the lowest 7 bits
of the word portion of any accumulator, upper 8 bits and
extension reg are sign extended, LSP portion is set to
“0”)
Signed 16-bit immediate data. When LC is the destina-
tion, use 13-bit values only.
Signed 16-bit immediate data move.
Move 16-bit immediate data to the last 64 locations of X
data memory-peripheral registers.
X:<<pp represents a 6-bit absolute I/O address.
Move 16-bit immediate date to a location within the first
64 words of X data memory.
X:aa represents a 6-bit absolute address.
