IP2022 User’s Manual—Instruction Set Architecture www.ubicom.com 109 ADD W,#lit8 Add W,Literal into W Operation: W = W + lit8 Bits affected: C, DC, Z Opcode: 0001 110f ffff ffff Description: This instruction adds an 8-bit literal value (a value
specified within the instruction) to the contents of
W and writes the 8-bit result into W. The operands
are treated as unsigned values. If the result of addition exceeds 0xFF, the C bit is
set  and  the  lower  eight  bits  of  the  result  are
written to W. Otherwise, the C bit is cleared. If there is a carry from bit 3 to bit 4, the DC (digit
carry) bit is set. Otherwise, the DC bit is cleared. If  the  result  of  addition  is zero, the Z  bit is  set.
Otherwise, the Z bit is cleared. A sum of 0x100 is
considered zero and therefore sets the Z bit. Cycles: 1
