+;* DESCRIPTION |
|
| 13 |
+;* When including this file in the assembly program file, all I/O register |
|
| 14 |
+;* names and I/O register bit names appearing in the data book can be used. |
|
| 15 |
+;* In addition, the two registers forming the data pointer Z have been |
|
| 16 |
+;* assigned names ZL - ZH. |
|
| 17 |
+;* |
|
| 18 |
+;* The Register names are represented by their hexadecimal address. |
|
| 19 |
+;* |
|
| 20 |
+;* The Register Bit names are represented by their bit number (0-7). |
|
| 21 |
+;* |
|
| 22 |
+;* Please observe the difference in using the bit names with instructions |
|
| 23 |
+;* such as "sbr"/"cbr" (set/clear bit in register) and "sbrs"/"sbrc" |
|
| 24 |
+;* (skip if bit in register set/cleared). The following example illustrates |
|
| 25 |
+;* this: |
|
| 26 |
+;* |
|
| 27 |
+;* in r16,PORTB ;read PORTB latch |
|
| 28 |
+;* sbr r16,(1<<PB6)+(1<<PB5) ;set PB6 and PB5 (use masks, not bit#) |
|
| 29 |
+;* out PORTB,r16 ;output to PORTB |
|
| 30 |
+;* |
|
| 31 |
+;* in r16,TIFR ;read the Timer Interrupt Flag Register |
|
| 32 |
+;* sbrc r16,TOV0 ;test the overflow flag (use bit#) |
|
| 33 |
+;* rjmp TOV0_is_set ;jump if set |
|
| 34 |
+;* ... ;otherwise do something else |
|
