Note: These become a multiplex bus only when all of the following conditions are satisfied:
• BYTE = “H”
• Multiplex bus select bit = “1”
• While the address which corresponds to chip select signal CS4 is accessed
Test conditions (Port Pi, f(XIN))
• VCC = 5 V±10 %
• Input timing voltage : VIL = 1.0 V, VIH = 4.0 V
• Output timing voltage : VOL = 0.8 V, VOH = 2.0 V, C
Test conditions (except Port Pi, f(XIN))
• VCC = 5 V±10 %
• Output timing voltage : VOL = 0.8 V, VOH = 2.0 V, C
• Data input : VIL = 0.8 V, VIH = 2.5 V
