_mul8l (Multiply, 8 Bit with 16 Bit Result)
This function multiplies two unsigned integers to produce a 16-bit result.
Stack Transformation: (a, b -- (a*b)(2))
Location: Near
Registers Affected: P0, P3
Example:
This example multiplies 50 times 40.
push #d’50 ; (d’50)
push #d’40 ; (d’40, d’50)
call _mul8l ; (d’208, 7)
_mul8ls (Multiply Signed, 8 Bit with 16 Bit Result)
This function multiplies two signed integers to produce a 16-bit signed result.
Stack Transformation: (a, b -- (a*b)(2))
Location: Near
Registers Affected: P0, P3
Example:
This example multiplies 50 times -40.
push #d’50 ; (d’50)
push #@lb(-d’40) ; (-d’40, d’50)
call _mul8ls ; (d’48, d’248)
_not16 (Not, 16 Bit)
This function returns the one’s complement (the bitwise NOT) of a 16-bit integer.
Stack Transformation: (a(2) -- ~a(2))
Location: Near
Registers Affected: None
Example:
This example returns the one’s complement of 8.
