Member Function Documentation

◆ chip()

void libsidplayfp::MOS656X::chip ( model_t model )

Set chip model.

◆ clearLightpen()

void libsidplayfp::MOS656X::clearLightpen ( )

Clears the lightpen usage flag.

◆ event()

void libsidplayfp::MOS656X::event ( )

overridevirtual

Event code to be executed. Events are allowed to safely reschedule themselves with the EventScheduler during invocations.

Implements libsidplayfp::Event.

◆ read()

uint8_t libsidplayfp::MOS656X::read ( uint_least8_t addr )

protected

Read VIC register.

Parameters

addr	Register to read.

◆ reset()

void libsidplayfp::MOS656X::reset ( )

Reset VIC II.

◆ triggerLightpen()

void libsidplayfp::MOS656X::triggerLightpen ( )

Trigger the lightpen. Sets the lightpen usage flag.

◆ write()

void libsidplayfp::MOS656X::write	(	uint_least8_t	addr,
		uint8_t	data
	)

protected

Write to VIC register.
