Detailed Description

HSK External Interrupt Routing headers.

This file offers functions to activate external interrupts and connect them to the available input pins.

Typedef Documentation

typedef ubyte hsk_ex_channel

Typedef for externel interrupt channels.

typedef ubyte hsk_ex_port

Typedef for externel interrupt ports.

Function Documentation

void hsk_ex_channel_disable ( const hsk_ex_channel channel )

Disables an external interrupt channel.

Parameters

channel The channel to disable, one of External Interrupt Channels

void hsk_ex_channel_enable	(	const hsk_ex_channel	channel,
		const ubyte	edge,
		const void(*)(void)	callback
	)

Enable an external interrupt channel.

It is good practice to enable a port for the channel first, because port changes on an active interrupt may cause an undesired interrupt.

The callback function can be set to 0 if a change of the function is not desired. For channels EXINT0 and EXINT1 the callback is ignored, implement interrupts 0 and 2 instead.

Parameters

channel	The channel to activate, one of External Interrupt Channels
edge	The triggering edge, one of External Interrupt Triggers
callback	The callback function for an interrupt event

Setting up EXINT0/1 is somewhat confusing. Refer to UM 1.1 section 5.6.2 to make sense of this.

void hsk_ex_port_close ( const hsk_ex_port port )

Disconnects an input port from an external interrupt.

Parameters

port	The port to close, one of External Interrupt Input Ports

void hsk_ex_port_open ( const hsk_ex_port port )

Opens an input port for an external interrupt.

Parameters

port	The port to open, one of External Interrupt Input Ports
