Functions and data structures for interrupts. Interrupts are controlled by registers IE and IE2 bits.
Interrupts at all can be enabled, disabled and readed by enable_mcu_interrupts(), disable_mcu_interrupts and is_mcu_interrupts_enabled() routines.
Each kind of interrupt source controlled by enable_<source>_interrupt, disable_<source>_interrupt routines. The state of each kind of interrupt source can be probed by is_<source>_interrupts_enabled() routine. If mcu interrupts support not enabled individual interrupt sources are disabled too and is_<source>_interrupts_enabled() call return false.
Interrupt handler should be declared as:
The name of handler routine can be any correct C function name. Hanlder should have empty parameter list. Keyword __interrupt and interrupt number assign handler to specified interrupt. See STC15series MCU Data Sheet Section 6.4.
