const byte * openmsx::MegaFlashRomSCCPlus::getReadCacheLine ( word start ) const

virtual

Test that the memory in the interval [start, start + CacheLine::SIZE) is cacheable for reading.

If it is, a pointer to a buffer containing this interval must be returned. If not, a null pointer must be returned. Cacheable for reading means the data may be read directly from the buffer, thus bypassing the readMem() method, and thus also ignoring EmuTime. The default implementation always returns a null pointer. The start of the interval is CacheLine::SIZE aligned.

Reimplemented from openmsx::MSXDevice.

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

virtual

Read a byte from a given IO port.

Reading via this method has no side effects (doesn't change the device status). If save 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.

byte openmsx::MegaFlashRomSCCPlus::peekMem	(	word	address,
		EmuTime::param	time
	)		const

virtual

Read a byte from a given memory location.

Reading memory via this method has no side effects (doesn't change the device status). If save 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 uses the cache mechanism (getReadCacheLine() method). If a certain region is not cacheable you cannot read it by default, Override this method if you want to improve this behaviour.

void openmsx::MegaFlashRomSCCPlus::powerUp ( EmuTime::param time )

virtual

This method is called when MSX is powered up.

The default implementation calls reset(), this is usually ok.

Parameters

time	The moment in time the power up occurs.
