Detailed Description

This class implements the MSX Turbo-R pause key.

Whenever the pause key is pressed a flip-flop is toggled. The status of this flip-flop can be read from io-port 0xA7. bit 0 indicates the status (1 = pause active) all other bits read 0

Member Function Documentation

◆ peekIO()

byte openmsx::MSXTurboRPause::peekIO	(	word	port,
		EmuTime::param	time
	)		const

overridevirtual

Read a byte from a given IO port.

Reading via this method has no side effects (doesn't change the device status). If safe reading is not possible this method returns 0xFF. This method is not used by the emulation. It can however be used by a debugger. The default implementation just returns 0xFF.

Reimplemented from openmsx::MSXDevice.

References openmsx::BooleanSetting::getBoolean().

◆ powerDown()

void openmsx::MSXTurboRPause::powerDown ( EmuTime::param time )

overridevirtual

This method is called when MSX is powered down.

The default implementation does nothing, this is usually ok. Typically devices that need to turn off LEDs need to reimplement this method.

Parameters

time	The moment in time the power down occurs.

◆ readIO()

byte openmsx::MSXTurboRPause::readIO	(	word	port,
		EmuTime::param	time
	)

overridevirtual

Read a byte from an IO port at a certain time from this device.

The default implementation returns 255.

◆ reset()

void openmsx::MSXTurboRPause::reset ( EmuTime::param time )

overridevirtual

This method is called on reset.

Default implementation does nothing.

◆ writeIO()

void openmsx::MSXTurboRPause::writeIO	(	word	port,
		byte	value,
		EmuTime::param	time
	)

overridevirtual

Write a byte to a given IO port at a certain time to this device.

The default implementation ignores the write (does nothing)
