Instruction Set Architecture—IP2022 User’s Manual 126 www.ubicom.com CMP W,#lit8 Compare W,Literal Operation: lit8 - W; result is discarded, STATUS is updated Bits affected: C, DC, Z Opcode: 0111 1001 kkkk kkkk Description: This instruction subtracts the contents of W from
an 8-bit literal and discards the result. W is left
unchanged.  Only  the  STATUS  register  bits  are
updated. If the result of subtraction is negative (W is larger
than lit8), the C bit is cleared and the lower eight
bits of the result are written to W. Otherwise, the
C bit is set. If there is a borrow from bit 3 to bit 4, the DC (digit
carry) bit is cleared. Otherwise, the bit is set. If the result of subtraction is zero, the Z bit is set.
Otherwise, the Z bit is cleared. Cycles: 1
