;   83C51FX processor definition file
;   =================================

; There has been much confusion about the mysterious IPH register at B7H!
; Old 83C51FX cores didn't have it.
; Old Intel "8-Bit Embedded Controllers" data books (1990) didn't mention
; it. Old Intel "Automotive Handbooks" used different names for it:
; IP1 (1989), and IPL (1990).
; The Intel "MCS 51 Microcontroller Family User's Manual" (February 1994)
; stated that the 80C51FA and 83C51FA still don't have it.
; However, the 87C51FA (erasable and OTP) implements an IPH, except early
; parts with lot numbers that don't end up with 'A'.
; The Philips 8xC51FA and 8xC51FB parts don't have the IPH register.
; Only the Philips 8xC51FC parts have! For maximum confusion, the Philips
; "80C51-Based 8-Bit Microcontrollers Data Handbook" (1994) doesn't
; describe any SFR for the 8xC51FA, provides an SFR table for the 8xC51FB
; (without an IPH), and a separate SFR table for the 8xC51FC (including
; an IPH, but at the wrong address B8H).
