1. The figure below shows how data from a ROM can be transferred to an external register. The ROM has the following timing parameters: tAcc = 250 ns and toe = 120 ns. Assume that the new address inputs have been applied to the ROM 70 ns before the occurrence of the TRASFER puse. Determine the minimum duration of the TRANSFER pulse for reliable transfer of data D7 Dy 0 Os DA 8-bit Di Do Transfer CS CLK
