C Language Features
you are using a powerup routine and will automatically generate code to jump to it after reset. If you
use a powerup routine, you will, however, need to add a jump to start after your initializations.
Refer to comments in the powerup source file for details about this. The powerup.as source file can
be found in the compilers SOURCES directory.
3.4 Supported Data Types and Variables
The HI-TECH PICC STD compiler supports basic data types with 1, 2, 3 and 4 byte sizes. Table
shows the data types and their corresponding size and arithmetic type.
3.4.1 Radix Specifiers and Constants
The format of integral constants specifies their radix. HI-TECH C supports the ANSI standard radix
specifiers as well as ones which enables binary constants to specified in C code. The format used to
specify the radices are given in Table 3.2. The letters used to specify binary or hexadecimal radices
are case insensitive, as are the letters used to specify the hexadecimal digits.
overflow. The suffix l or L may be used with the constant to indicate that it must be assigned either
a signed long or unsigned long type, and the suffix u or U may be used with the constant to
indicate that it must be assigned an unsigned type, and both l or L and u or U may be used to indicate
unsigned long int type.
constant. The suffixes l or L specify a long double type which is considered an identical type to
Any integral constant will have a type which is the smallest type that can hold the value without
Floating-point constants have double type unless suffixed by f or F, in which case it is a float
