Subject: Remove AOUT bytecode instruction
X-Git-Url: https://git.the-white-hart.net/?a=commitdiff_plain;h=f363d8018be4441b5ef45f31557b0bde3326460e;p=atmega%2Fsiggen.git

Remove AOUT bytecode instruction

All the PWM-capable pins will be used for other things in my final
design, so no need for this in my application.
