◆ _CPU_Fatal_halt
| #define _CPU_Fatal_halt | ( | _source, | |
| _error | |||
| ) |
◆ _CPU_ISR_Flash
| #define _CPU_ISR_Flash | ( | _level | ) |
Value:
do{ \
_CPU_ISR_Enable( _level ); \
_OR1K_mtspr(CPU_OR1K_SPR_SR, (_level & ~CPU_OR1K_SPR_SR_IEE)); \
} while(0)
◆ CPU_SIZEOF_POINTER [1/2]
| #define CPU_SIZEOF_POINTER 4 |
Size of a pointer.
This must be an integer literal that can be used by the assembler. This value will be used to calculate offsets of structure members. These offsets will be used in assembler code.
◆ CPU_SIZEOF_POINTER [2/2]
| #define CPU_SIZEOF_POINTER 4 |
Size of a pointer.
This must be an integer literal that can be used by the assembler. This value will be used to calculate offsets of structure members. These offsets will be used in assembler code.
