Opcode map field used...	For operand type...	Unit
src	ucst4	none

Description	src is encoded as count − 1. For src + 1 cycles, no operation is performed. The
	maximum value for count is 9. NOP with no operand is treated like NOP 1 with
	src encoded as 0000.
	A multicycle NOP will not finish if a branch is completed first. For example, if
	a branch is initiated on cycle n and a NOP 5 instruction is initiated on cycle
	n + 3, the branch is complete on cycle n + 6 and the NOP is executed only from
	cycle n + 3 to cycle n + 5. A single-cycle NOP in parallel with other instructions
	does not affect operation.
Execution	No operation for count cycles
Instruction Type	NOP
Delay Slots	0
