SpeedSwitch

Struct SpeedSwitch

pub struct SpeedSwitch(/* private fields */);

Available on crate feature cgb only.

Expand description

CPU speed switch (KEY1).

Bit	Field	Access	Meaning
7	`double_speed`	RO	Currently in CGB double speed mode.
6-1	—		Unused.
0	`armed`	R/W	Arm a speed switch; it takes effect on the next `STOP`.
