True, but the 320*16* CPU rev K was released some time ago. I suspect that is what J. R. was referring to. They made it to rev N on that part before it more-or-less stabilized. > The latest 32082 MMU rev is M. >The errata (excuuse me, "User Information") sheet for the Rev M >32082, dated 8th August 1985, says that "physical breakpoints >cannot be used reliably". > >However the part definitely still contains two breakpoint registers.
