Assembler Syntax

#u16

• DR.L → DR.L

AND #u16,DR.L

#u16

• DR.H → DR.H

AND #u16,DR.H

AND #u16,DR.L

Performs a bitwise AND on an immediate unsigned word and the contents of the LP of a source data or
address register (DR). Stores the result in the LP of the data or address register (DR). The HP of the register
is unaffected.

Note:

This instruction is assembler-mapped to BMCLR #~u16,DR.L where #~u16 is the bitwise
complement of #u16.

AND #u16,DR.H

Performs a bitwise AND on an immediate unsigned word and the contents of the HP of a data or address
register (DR). Stores the result in the HP of the data or address register (DR). The LP of the register is
unaffected.

Note:

This instruction is assembler-mapped to BMCLR #~u16,DR.H.
