20 ; User-defined Power-On Initialization of Memory
21 ;
22 ; With the following EQU statements the initialization of memory
23 ; at processor reset can be defined:
24 ;
25 ; ; the absolute start-address of IDATA memory is always 0
0100 26 IDATALEN EQU 100H ; the length of IDATA memory in bytes.
27 ;
0000 28 XDATASTART EQU 0H ; the absolute start-address of XDATA memory
0000 29 XDATALEN EQU 0H ; the length of XDATA memory in bytes.
30 ;
31 ; Notes: The IDATA space overlaps physically the DATA and BIT areas of the
32 ; LPC9xx device.

36 ; Reentrant Stack Initilization
37 ;
38 ; The following EQU statements define the stack pointer for reentrant
39 ; functions and initialized it:
40 ;
41 ; Stack Space for reentrant functions in the SMALL model.
0000 42 IBPSTACK EQU 0 ; set to 1 if small reentrant is used.
0100 43 IBPSTACKTOP EQU 0FFH+1 ; set top of stack to highest location+1.
44 ;
45 ; Stack Space for reentrant functions in the LARGE model.
0000 46 XBPSTACK EQU 0 ; set to 1 if large reentrant is used.
0200 47 XBPSTACKTOP EQU 01FFH+1 ; set top of stack to highest location+1.
48 ;
49 ; Stack Space for reentrant functions in the COMPACT model.
0000 50 PBPSTACK EQU 0 ; set to 1 if compact reentrant is used.
0100 51 PBPSTACKTOP EQU 0FFH+1 ; set top of stack to highest location+1.
