6 ; INIT_TNY.A51: This code is executed, if the application program contains
7 ; initialized variables at file level. This file is a reduced version of the
8 ; INIT.A51 file and can be used for projects that do not contain XDATA memory
9 ; initilizations.
10 ;
11 ; If you are using uVision2, just add the file as last file to your project.
12 ; *** IMPORTANT NOTE ***: this file needs to be the last file of the linker
13 ; input list. If you are using uVision2 this file should be therefore the
14 ; last file in your project tree.can

21 ; To link the modified INIT.OBJ file to your application use the following

28 ; User-defined Watch-Dog Refresh.
29 ;
30 ; If the C application contains many initialized variables uses a watchdog
31 ; it might be possible that the user has to include a watchdog refresh into
32 ; the initialization process. The watchdog refresh routine can be included
33 ; in the following MACRO and can alter all CPU registers except
34 ; DPTR.

36 WATCHDOG MACRO
37 ; Include any Watchdog refresh code here

133 ; STRUCTURE OF THE INITIALIZATION INFORMATION
134 ; -------------------------------------------
135 ; This section describes the initialization data generated by C51 for
136 ; explicit variable initializations (in segment ?C_INITSEC).
137 ;
138 ; Explicit variable initilizations at C source level are stored by C51 in
139 ; the segment ?C_INITSEC. All partial segments are combined at linker level
140 ; to one segment. The segment end value DB 0 is taken from this library module
141 ; INIT.A51.
142 ;
143 ; Structure of the ?C_INITSEC information:
144 ; <Info> (see below) [BYTE] ----+ repeated
145 ; <additional info> [BYTES depend on Info] ----+ repeated
146 ; 0x00 [BYTE] <end of list mark>
147 ;
148 ; <Info> has the following format:
149 ;
150 ; Bit 7 6 5 4 3 2 1 0
151 ; <Info> T T B L L L L L T=Type B=BIGBIT L=LENGTH
152 ;
153 ; If BIGBIT is set, another LENGTH BYTE FOLLOWS. The LENGHT
154 ; info of the first byte is then the HIGH part.
155 ;
156 ; Typ is one of the following:
157 ; 0 := IDATA init values; the following bytes follow:
158 ; - 1 byte address
159 ; - init data bytes according LENGTH specification
160 ;
161 ; 1 := XDATA init values; the following bytes follow:
162 ; - 2 byte address (high byte first)
163 ; - init data bytes according LENGTH specification
164 ;
165 ; 2 := PDATA init values; the following bytes follow:
166 ; - 1 byte address
167 ; - init data bytes according LENGTH specification
168 ;
169 ; 3, BIGBIT=0 := BIT init values; the followign bytes follow:
170 ; - 1 byte for each bit according LENGTH specification
171 ; this byte has the following format:
172 ;
173 ; Bit 7 6 5 4 3 2 1 0
174 ; I B B B B B B B I := state of the bit
175 ; B := bit address
176 ;
177 ; 3, BIGBIT=1 := HDATA init values; the following bytes follow:
178 ; - another LENGTH byte (since BIGBIT is always 1)
179 ; - 3 byte address (MSB first)
180 ; - data bytes according LENGTH specification
181 ;
