Description : Video Decoder and System Controller (with JTAG) View

The Video Decoder and System Controller with JTAG (VDSC/JTAG) is a CMOS device integrating a 680X0 family System Controller and video graphics decoder, see Figure 1–1 below.
The MCD212 is a programmable, multi–scan video device that can function as either a master or a slave. It is functionally equivalent to the MCD211 with the addition of JTAG testing. The MCD212 is a drop–in replacement for the MCD211 if the JTAG functionality is not required. It can directly drive up to 5M bytes1 of memory and provides chip–select signals for System ROM and peripherals. The on–chip DRAM Controller can support up to 4M bytes DRAM and controls access to the unspecialized System or Video DRAM. The CPU can access any memory location, even during active video display lines, thereby boosting System performance.
