;	Rev 7.2		G. Boehm, MRI, November 25, 1991
;			Unify register numbering between XHM & XDM

;			Digitailor Merge (RTOS)

;
;	New rev #1.1	J. Fuchigami, MRI, March 19, 1991
;			Put under SCCS
;
; ------- DIGITAILOR REVS -------
; 
;    Rev 1.4   19 Jul 1991 11:07:20   kjell
; New breakpoint status defined: STAT_IA, used to report hardware breakpoints
;   when the execution is stopped *after* the execution of the instruction.
; 
;    Rev 1.3   14 Jun 1991 15:59:58   kjell
; New constants: UTL_SETREG, UTL_GETREG, UTL_RESET, UTL_REINIT, EXE_EVENT, 
;   CORTOS, CH_FIRST, EXE_GO_MODE, EXE_TRACE_MODE, MODE_NORM, MODE_RTOS, 
;   IDLE_RX, IDLE_TX, IDLE_SUM, IDLE_INI, ER_TOUT, MON_MESSAGE, ER_MESSAGE, 
;   MON_PARSE, ER_PARSE, MON_VALUE, ER_VALUE.
; New fields in config-table: cfutlhk, cfsushk (replaced cfrmbz2, cfrmbz3)
; The definitions for all register numbers (REG_xx) are now available.
; 
;    Rev 1.2   26 May 1990 14:56:58   Kjell_Christenson,_Digitailor_AB
; New config field CFEXTHK for extension hook (RMBZ2).
; New config field CFUSRCODE (RMBZ3) to supply start address of monitor-
;  support-code. This is only provided if it is immediately before mon_start.
;  It is used to protect writes into the Monitor and support code by XRAY.
; Two new reserved field added to config table (RMBZ2 & RMBZ3).
; 
;    Rev 1.1   21 May 1990 17:49:18   Kjell Christenson, DIGITAILOR AB
; Correction of bad valued for constants CCPUV20 and up.
; New constants: INI_INIT, INI_REINIT, MOREINIT, COCALLRST..
; 
;    Rev 1.0   06 Apr 1990 15:46:40   Kjell Christenson, DIGITAILOR AB
