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 register are sign extended, LSP
portion is set to 0).
Signed 7-bit integer data (data put in the low por-
tion of the word).
Signed 16-bit immediate data.
Move to C2, D2, C0, D0 registers.
Move 16-bit immediate data to the one of 64 loca-
tions in X data memory—peripheral registers.
Move 16-bit immediate data to the first 64 locations
of X data memory.
Unsigned 16-bit immediate data.
Sign extend 16-bit value and move to 32-bit mem-
ory location.
Move to 32-bit memory location.
Signed 5-bit integer data (data is put in the lowest 5
bits of the word portion of the register; upper bits
are sign extended).
Sign extend the 16-bit immediate data to 36 bits
when moving to an accumulator; sign extend to
24 bits when moving to an AGU register.
Use MOVEU.W for moves to the AGU with
unsigned 16-bit immediate data.
Move signed 32-bit immediate data to a 32-bit
accumulator.
Move unsigned 24-bit immediate value to AGU reg-
ister.
