Member Function Documentation

◆ allowUnaligned()

bool openmsx::MSXVictorHC9xSystemControl::allowUnaligned ( ) const
overridevirtual

By default we don't allow unaligned <mem> specifications in the config file.

Though for a machine like 'Victor HC-95A' is it useful to model it with combinations of unaligned devices. So we do allow it for a select few devices: devices that promise to not call any of the 'fillDeviceXXXCache()' methods.

Reimplemented from openmsx::MSXDevice.

◆ peekMem()

byte openmsx::MSXVictorHC9xSystemControl::peekMem ( word  address,
EmuTime::param  time 
) const
overridevirtual

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.

◆ readMem()

byte openmsx::MSXVictorHC9xSystemControl::readMem ( word  address,
EmuTime::param  time 
)
overridevirtual

Read a byte from a location at a certain time from this device.

The default implementation returns 255.

◆ writeMem()

void openmsx::MSXVictorHC9xSystemControl::writeMem ( word  address,
byte  value,
EmuTime::param  time 
)
overridevirtual

Write a given byte to a given location at a certain time to this device.

The default implementation ignores the write (does nothing).
