; Reentrant Stack Initialization ;

; The following EQU statements define the stack pointer for reentrant ; functions and initialized it: ;

; Stack Space for reentrant functions in the SMALL model. ; IBPSTACK: Enable SMALL model reentrant stack

; Stack space for reentrant functions in the SMALL model.

IBPSTACK EQU 0 ; set to 1 if small reentrant is used. ; IBPSTACKTOP: End address of SMALL model stack <0x0-0xFF> ; Set the top of the stack to the highest location.

IBPSTACKTOP EQU 0xFF +1 ; default 0FFH+1 ; ;

; Stack Space for reentrant functions in the LARGE model. ; XBPSTACK: Enable LARGE model reentrant stack

; Stack space for reentrant functions in the LARGE model.

XBPSTACK EQU 0 ; set to 1 if large reentrant is used. ; XBPSTACKTOP: End address of LARGE model stack <0x0-0xFFFF> ; Set the top of the stack to the highest location.

XBPSTACKTOP EQU 0xFFFF +1 ; default 0FFFFH+1 ; ;

; Stack Space for reentrant functions in the COMPACT model. ; PBPSTACK: Enable COMPACT model reentrant stack

; Stack space for reentrant functions in the COMPACT model.

PBPSTACK EQU 0 ; set to 1 if compact reentrant is used. ;

; PBPSTACKTOP: End address of COMPACT model stack <0x0-0xFFFF> ; Set the top of the stack to the highest location.

PBPSTACKTOP EQU 0xFF +1 ; default 0FFH+1 ; ;

; Define the XDATA page used for PDATA variables.

; PPAGE must conform with the PPAGE set in the linker invocation. ;

; Enable pdata memory page initalization
