According to the National Semiconductor 32000 Instruction Set Reference Manual the instruction ... extw r0, 0(r1), r2, 7 produces the code: 2E 81 40 00 07. I say that it should be ... 2E 81 48 00 07. Is this indeed a typo or am I constructing the instruction incorrectly??? Could someone please run this through a 32000 assembler and let me know what the true encoding for extw... is? Harry Reed.

I just ran this through the assembler on a Tektronix 6130 and it agrees with you. The manual is in error. -- Andrew Klossner (decvax!tektronix!orca!andrew) [UUCP] (orca!andrew.tektronix@csnet-relay) [ARPA]
