Hi, etwas hat mich gerade ziemlich zum Staunen gebracht - folgender Code: reset: clr _0 ldiw X, RAMTOP ;Clear RAM ldi AL, 0 ; st X+, _0 ; dec AL ; brne PC-2 ; ; outi OSCCAL, 172 ;Adjust OSCCAL if needed. outi PORTB, 0b001101 ;Initalize Port B; PB3 to 1 for LED outi DDRB, 0b011010 ; outi PLLCSR, 0b00000110 ;Initialize TC1 in 250 kHz fast PWM mode. outi TCCR1, 0b01100001 ;Connect TC1 to OC1A outi GTCCR, 0b01100000 ;Connect TC1 to OC1B outi OCR0A, 62 ;Initalize TC0 in 32 kHz interval timer. outi TCCR0A, 0b00000010 outi TCCR0B, 0b00000010 outi TIMSK, (1<<OCIE0A) start_play: ldiw Z, score*2 cli clrw _Tmr clr _TmrS sei pl_next: lpmw B, Z+ rcall drv_decay cli cpw _Tmr, B sei brcs PC-5 pl_note: lpm CL, Z+ cpi CL, EoS breq sleep_handler mov AL, CL rcall note_on andi CL, en breq pl_note rjmp pl_next sleep_handler: .DEF PWR_DOWN = R16 ldi r18, 3 cpi r18, 3 BRNE start_play LDI PWR_DOWN, (1<<SE) | (1<<SM1) | (0<<SM0) OUT MCUCR, PWR_DOWN outi PORTB, 0 SLEEP Folgender Sachverhalt: Es geht um "sleep_handler" - da r18 == 3 ist, wird wie erwartet der Chip in den Sleep-Mode versetzt. Aber! Wird die Codezeile "ldi r18, 3" jedoch zum Beispiel in die "reset"-section ganz am Anfang verschoben, dann wird "BRNE start_play" immer condition true executed, obwohl r18 == 3 ist. Warum??? Es kann doch wohl nicht sein, dass Registerwerte nur innerhalb eines Labels erhalten bleiben oder? Es gib zwar auch ein paar Subroutine-Calls, aber das sollte nicht das Problem sein, denn R18 nirgendwo weiter verwendet, und selbst wenn sollte es ja auf dem Stack gesichert sein. Komisch, komisch. verwirrt
Gibts noch mehr Code, vielleicht welcher der R18 streichelt, oder ist das wirklich alles? Ausserdem sieht man den Makros und Symbolen nicht an, was sich dahinter verbirgt.
Nein, es gibt mehr, habe wegen der Übersicht nicht alles gepostet.
