12 ;* Target MCU :ATtiny26
\r
15 ;* When including this file in the assembly program file, all I/O register
\r
16 ;* names and I/O register bit names appearing in the data book can be used.
\r
17 ;* In addition, the six registers forming the three data pointers X, Y and
\r
18 ;* Z have been assigned names XL - ZH. Highest RAM address for Internal
\r
19 ;* SRAM is also defined
\r
21 ;* The Register names are represented by their hexadecimal address.
\r
23 ;* The Register Bit names are represented by their bit number (0-7).
\r
25 ;* Please observe the difference in using the bit names with instructions
\r
26 ;* such as "sbr"/"cbr" (set/clear bit in register) and "sbrs"/"sbrc"
\r
27 ;* (skip if bit in register set/cleared). The following example illustrates
\r
30 ;* in r16,PORTB ;read PORTB latch
\r
31 ;* sbr r16,(1<<PB6)+(1<<PB5) ;set PB6 and PB5 (use masks, not bit#)
\r
32 ;* out PORTB,r16 ;output to PORTB
\r
34 ;* in r16,TIFR ;read the Timer Interrupt Flag Register
\r
35 ;* sbrc r16,TOV0 ;test the overflow flag (use bit#)
\r
36 ;* rjmp TOV0_is_set ;jump if set
\r
37 ;* ... ;otherwise do something else
