Instruction Set Architecture—IP2022 User’s Manual 132 www.ubicom.com CSNE W,#lit8 Compare W,Literal then Skip if Not Equal Operation: lit8 - W; if result is not zero, skip next instruction Bits affected: None Opcode: 0111 0110 kkkk kkkk Description: This instruction subtracts the contents of W from
an 8-bit literal and discards the result. W is left
unchanged. If the result is nonzero (i.e. W and the
literal are not equal), the following instruction is
skipped.   The   STATUS   register   bits   are   not
updated. Cycles: 1 Example: csne  w,#0x1B;compare W against                                       ;escape char.
jmp    escape_char;if equal, jump                                       ;to escape_char
jmp    normal_char;else, jump to ;normal_char This example compares the contents of W with
the  ASCII  code  for  the  escape  character.  If  W
holds 0x1B, then the escape_char routine is
