A
Bootstrap Program
This appendix lists the bootstrap program and equates for the DSP56309. Freescale posts updates
to the bootstrap program on the Worldwide Web at the web site listed on the back cover of this
manual.
A.1 Bootstrap Code
; BOOTSTRAP CODE FOR DSP56309 - (C) Copyright 1997 Motorola Inc.
; Revised March, 18 1997.
;
; Bootstrap through the Host Interface, External EPROM or SCI.
;
; This is the Bootstrap program contained in the DSP56309 192-word Boot
; ROM. This program can load any program RAM segment from an external
; EPROM, from the Host Interface or from the SCI serial interface.
;
;
;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;
; If MD:MC:MB:MA=x000,
then
the Boot ROM is bypassed
and the DSP56309
; will start fetching instructions
beginning with address $C00000 (MD=0)
; or $008000
(MD=1)
assuming
that
an external memory of SRAM type is
; used. The accesses will be performed using
31 wait states with no
; address attributes selected (default area).
;
;
;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;
; Operation modes MD:MC:MB:MA=0001-0111 are reserved.
;
;
;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;
; If MD:MC:MB:MA=1001, then it loads a program RAM segment from consecutive
; byte-wide P memory locations, starting at P:$D00000 (bits 7-0).
; The memory is selected by the Address Attribute AA1 and is accessed with
; 31 wait states.
; The EPROM bootstrap code expects to read 3 bytes
; specifying the number of program words, 3 bytes specifying the address
; to start loading the program words and then 3 bytes for each program
; word to be loaded. The number of words, the starting address and the
; program words are read least significant byte first followed by the
; mid and then by the most significant byte.
; The program words will be condensed into 24-bit words and stored in
; contiguous PRAM memory locations starting at the specified starting address.
; After reading the program words, program execution starts from the same
; address where loading started.
