Table 2−11. Shift Operations (Continued)
Operation Type
Store 16 LSBs of shifted P. P is shifted
as per the PM bits. The 16 LSBs of shifter
are stored. Syntax:
MOV loc16, P
Store 16 MSBs of shifted P. P is shifted
as per the PM bits. The result is shifted
right by 16 so that its 16 MSBs are in the
16 LSBs of the shifter. 16 LSBs of shifter
are stored. Syntax:
MOVH loc16, P
