; 
; This is an example STARTUP file. 
; @(#)cstart.a96      1.4 (nt-ef) 
; 
; To Assemble: 
;	asm196 cstart.a96 oj(cstart.obj) cmain model(nt) 
; The 'cmain' control will allow symbol 'main' to be used. 
; 
; If FPAL96 is used, enable the calling of 'fpinit'. 
; 
; Read Chapter 13 of Intel's 8xC196NT Microcontroller User's 
; Manual very carefully. 
; It tells you exactly how to access external memory, as this 
; determines the usage of EPORT and P5. 
; (Intel User's Manual Order number: 272317-002) 
; Note that an example initialization is given below in comment.
