# Model-specific constants
Model-specific constants must be loaded separately. Here is a
list of units:
- ATMega328P: B65-B66
Those units contain register constants such as PORTB, DDRB, etc.
Unlike many moder assemblers, they do not include bit constants.
Here's an example use:
DDRB 5 SBI,
PORTB 5 CBI,
R16 TIFR0 IN,
R16 0 ( TOV0 ) SBRS,
# AVR instructions list
