CRTC

104 bytes removed, 14 November
/* DISPTMG (aka Display Enable) */
The DISPTMG signal is composited from its 3 internal subcomponents: HBORDER (Horizontal), VBORDER (Vertical), IBORDER (Immediate) by using the NOR function. DISPTMG is "0" if at least one of its subcomponents is "1". These 3 subcomponents are all independent of each other.
 
On CRTC 2, when HSYNC is active, the condition HCC=0 does not disable HBORDER, unlike the other CRTCs.
