Микроконтроллеры

RTFM и ветеранам, оказывается, не помешает :) Функциями в AVRASM несколько недальновидно назвали расширенные операторы. Вот цитата из файла AVRASM.chm: Functions The following functions are defined: LOW(expression) returns the low byte of an expression HIGH(expression) returns the second byte of an expression BYTE2(expression) is the same function as HIGH BYTE3(expression) returns the third byte of an expression BYTE4(expression) returns the fourth byte of an expression LWRD(expression) returns bits 0-15 of an expression HWRD(expression) returns bits 16-31 of an expression PAGE(expression) returns bits 16-21 of an expression EXP2(expression) returns 2 to the power of expression LOG2(expression) returns the integer part of log2(expression) The following functions are only defined in AVRASM2: INT(expression) Truncates a floating point expression to integer (ie discards fractional part) FRAC(expression) Extracts fractional part of a floating point expression (ie discards integer part). Q7(expression) Converts a fractional floating point expression to a form suitable for the FMUL/FMULS/FMULSU instructions. (sign + 7-bit fraction) Q15(expression) Converts a fractional floating point expression to a form suitable for the FMUL/FMULS/FMULSU instructions. (sign +15-bit fraction) ABS() Returns the absolute value of a constant expression.
