C++ (Cpp) set_line_value Examples

Example #1

File: dragon_fdc.cpp Project: RafTacker/mame

void dragon_fdc_device_base::update_lines()
{
	// set the NMI line
	set_line_value(line::NMI, intrq() && (dskreg() & 0x20));

	// set the CART line
	set_line_value(line::CART, drq());
}

Example #2

File: coco_fdc.cpp Project: qwijibo/mame

void coco_fdc_device_base::update_lines()
{
	// clear HALT enable under certain circumstances
	if (intrq() && (dskreg() & 0x20))
		set_dskreg(dskreg() & ~0x80);  // clear halt enable

	// set the NMI line
	set_line_value(line::NMI, intrq() && (dskreg() & 0x20));

	// set the HALT line
	set_line_value(line::HALT, !drq() && (dskreg() & 0x80));
}

Example #3

{
	LOG("%s()\n", FUNCNAME );
	auto cart_line = line_value::Q;
	set_line_value(line::CART, cart_line);
