__CPUmacro__
cated by "product type specification" in the device file with "_ _" prefixed and "_" or
"_ _"suffixed is defined.
Register mode macro

Macro defined with register mode is as follows.
32 register mode:
__reg32__
26 register mode:
__reg26__
22 register mode:
__reg22__
Universal register mode: __reg_common__
__MULTI_CORE__

__MULTI_CMN__

C99 language function
This section describes the C99 language functions supported by the CX.
(1) Macros with variable numbers of arguments
The compiler supports C preprocessor macros with variable numbers of arguments.
#define pr (fmt, ...)
printf (fmt, __VA_ARGS__)
The notation above can be used to describe an arbitrary number of arguments.
pr ("%s%d\n", "aa", 1)
->
printf ("%s%d\n", "aa", 1)
pr ("%d\n", 2)
->
printf ("%d\n", 2)
(2) _Bool type
_Bool type is supported.
(3) Comment by //
Text from two slashes (//) until a newline character is a comment. If there is a backslash character (\) immediately
before the newline, then the next line is treated as a continuation of the current comment.
(4) Inline keyword (inline function)
Inline function is supported.
This can also be specified using a pragma directive, via the following format.
#pragma inline
function-name[, function-name, ...]
For the details of expansion specification, see "(9) Inline expansion".
