ANDH, ANDL – Logical AND into high or low half of register
Architecture revision:
Architecture revision1 and higher.
Description
Performs a bitwise logical AND between the high or the low halfword in the specified register and
a constant. The result is stored in the high or the low halfword of the destination register while
the other bits remain unchanged. The Clear Other Half (COH) parameter allows the other half to
be cleared.
Operation:
I.
Rd[31:16]
← Rd[31:16] ∧ imm16;
II.
Rd[31:16]
← Rd[31:16] ∧ imm16;
Rd[15:0]
← 0;
III.
Rd[15:0]
← Rd[15:0] ∧ imm16;
IV.
Rd[15:0]
← Rd[15:0] ∧ imm16;
Rd[31:16]
← 0;
