Member Function Documentation

byte * openmsx::RomAscii8kB::getWriteCacheLine ( word start ) const

virtual

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

If it is, a pointer to a buffer containing this interval must be returned. If not, a null pointer must be returned. Cacheable for writing means the data may be written directly to the buffer, thus bypassing the writeMem() 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::MSXRom.

void openmsx::RomAscii8kB::reset ( EmuTime::param time )

virtual

This method is called on reset.

Default implementation does nothing.
