Arguments

blank When not FALSE, the LCD screen will be set to display white

Description

When not FALSE, this function uses the CPU to force termination of the 2D graphics circuit. During a forced blank, the 2D graphics circuit will not access VRAM and the LCD screen will be set to display white. However, the internal HV sync counters are operating even during a forced blank. When the internal HV sync counters change the force blank during the display period, switching from ON to OFF will take place immediately after setting; switching from OFF to ON will take place at the beginning of the third line after the setting.
