DESCRIPTION
;* When
including this file in the assembly program file, all I/O register
;*
names and I/O register bit names appearing in the data book can be used.
;* In
addition, the six registers forming the three data pointers X, Y and
;* Z
have been assigned names XL - ZH. Highest RAM address for Internal
;* SRAM
is also defined
;*
;* The
Register names are represented by their hexadecimal address.
;*
;* The
Register Bit names are represented by their bit number (0-7).
;*
;*
Please observe the difference in using the bit names with instructions
;* such
as "sbr"/"cbr" (set/clear bit in register) and
"sbrs"/"sbrc"
;*
(skip if bit in register set/cleared). The following example illustrates
;*
this:
;*
;* in r16,PORTB ;read PORTB latch
;* sbr r16,(1<<PB6)+(1<<PB5) ;set PB6 and PB5 (use masks, not bit#)
;*
out PORTB,r16 ;output to PORTB
;*
;* in r16,TIFR ;read the Timer Interrupt Flag Register
;* sbrc r16,TOV0 ;test the overflow flag (use bit#)
;* rjmp TOV0_is_set ;jump if set
;* ... ;otherwise do something else
