The user may use the following syntax to associate a variable with the TPR register:

struct tpr_struct <varname> @ tpr;

Entry table intrinsic functions

●

Enable_match()/Disable_match(): Sets or clears the ME bit in the entry table entries

which are associated with the thread.

●

preload_p01()/preload_p23(): Sets or clears the PP bit in the entry table entries, which

are associated with the thread.

Note:

These functions are implemented only for backward compatibility. It is better not to use them

since if they are omitted, the compiler computes the best preload option itself and optimizes

the code accordingly.

●

read_match(): Loads the values of the Match registers into ERTA and ERTB.

23.9

Predefined symbols

The compiler supports the following predefined symbols:

23.10

Integer types

All standard C types are supported.

Two new integer data types are created such as int24, which would be the default for int and

unsigned int24, which would be the default for unsigned int.

long and unsigned long are the native types for 32 bits.

The following identifiers are also supported: _Bool, int8, int16, int32, int8_t, int16_t, int24_t,

int32_t, uint8, uint16, uint32, uint8_t, uint16_t, uint24_t, uint32_t.
