CPDT		data transfer instructions

		LDF, STF, LFM, SFM

CPDO		dyadic arithmetic instructions

		ADF, MUF, SUF, RSF, DVF, RDF,

		POW, RPW, RMF, FML, FDV, FRD, POL

CPDO		monadic arithmetic instructions

		MVF, MNF, ABS, RND, SQT, LOG, LGN, EXP,

		SIN, COS, TAN, ASN, ACS, ATN, URD, NRM

CPRT		joint arithmetic/data transfer instructions

		FIX (arithmetic followed by load/store)

		FLT (load/store followed by arithmetic)

W		write back bit: 1 = update base register (Rn)

L		load/store bit: 0 = store, 1 = load

Rn		base register

Fd		floating point destination register

Fn		floating point source register

Fm		floating point source register or floating point constant
