TECHNICAL DATA MC2672 Advance Information Programmable Video Timing Controller (PVTC) The MC2672 programmable video timing controller (PVTC) is a programmable device designed for use in CRT terminals and displays systems that employ raster scan techniques. The PVTC generates the vertical and horizontal timing signals necessary for the display of interlaced or non-interlaced data on a CRT monitor. It provides consecutive addressing to a user specified display buffer memory domain and controls the CPU-display buffer interface for various buffer configuration modes. A variety of operating modes, display formats, and timing profiles can be implemented by programming the control registers in the PVTC. Applications include CRT terminals, word-processing systems, small business computers, and home computers. 4 MHz Character Rate Up to 256 Characters Per Row 1 to 16 Raster Lines Per Character Row Up to 128 Character Rows Per Frame Programmable Horizontal and Vertical Sync Generators Interlaced or Non-Interlaced Operation Up to 16K RAM Addressing for Multiple Page Operation Automatic Wraparound of RAM Addressable, Incrementable, and Readable Cursor Programmable Cursor Size, Position, and Blink Split Screen and Horizontal Scroll Capability Light Pen Register Selectable Buffer Interfce Modes Dynamic RAM Refresh Completely TIL Compatible Single + 5-Volt Power Supply Power-On...
