;  'RTX-51 tiny' Hardware-Timer
;  ============================
;
;  With the following EQU statements the initialization of the 'RTX-51 tiny'
;  Hardware-Timer can be defined ('RTX-51 tiny' uses the 8051 Timer 0 for 
;  controlling RTX-51 software timers).
;
;		; define the register bank used for the timer interrupt.
INT_REGBANK	EQU	1	; default is Registerbank 1
;
;		; define Hardware-Timer Overflow in 8051 machine cycles.
INT_CLOCK	EQU	10000	; default is 10000 cycles
;
;		; define Round-Robin Timeout in Hardware-Timer Ticks.
TIMESHARING	EQU	5	; default is 5 ticks.
;		; 
;		; note: Round-Robin can be disabled by using value 0.
;
;  Note:   Round-Robin Task Switching can be disabled by using '0' as
;          value for the TIMESHARING equate.
;------------------------------------------------------------------------------
;
;  'RTX-51 tiny' Stack Space
;  =========================
;
;  The following EQU statements defines the size of the internal RAM used
;  for stack area and the minimum free space on the stack.  A macro defines
;  the code executed when the stack space is exhausted.
;
;		; define the highest RAM address used for CPU stack
RAMTOP		EQU	0FFH	; default is address (256-1)
;
FREE_STACK	EQU	20	; default is 20 bytes free space on stack
;
STACK_ERROR	MACRO
		CLR	EA	; disable interrupts
		SJMP	$	; endless loop if stack space is exhausted
		ENDM
