For fast memory data manipulation, the Z86251 offers segmented base registers. The device also features DRAM memory control and refresh logic. The Z86251 provides a number of important peripheral functions, such as the IR Blaster to send command signals to the VCR, and low-power management to avoid loss of data. The DBE is optimized to work with Zilog's Z89300 series of TV controller devices to provide a cost-effective solution for StarSight programming-guide data extraction and display. Notes: All Signals with a preceding front slash, "/", are active Low, e.g.: B//W (WORD is active Low); /B/W (BYTE is active Low, only).
