Detailed Description

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:

void interruptHandler() __interrupt(0)

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.

#	Description
0	INT0
1	Timer0 interrrupt
2	INT1
3	Timer1 interrupt (STC15W408AS has no this timer)
4	UART1 interrupt
5	ADC interrupt
6	Low voltage detection (LVD) interrupt
7	PCA interrupt
8	UART2 interrupt
9	SPI interrupt
10	INT2
11	INT3
12	Timer2 interrupt
13	PWM interrupt
16	INT4
17	UART3 (STC15W408AS has no this timer)
18	UART4 (STC15W408AS has no this timer)
19	Timer3 interrupt (STC15W408AS has no this timer)
20	Timer4 interrupt (STC15W408AS has no this timer)
21	Comparator interrupt

For interrupt priority set_<source>_interrupt_priority(priority enum value) and get _<source>_interrupt_priority() routines should be used.

For INT0 and INT1 trigger configration set_<int0 or int1>_interrupt_trigger(trigger enum value) and get_<int0 or int1>_interrupt_trigger() routines should be used.
