(7) Bus Timing (PC card mode, I/O read cycle)
(VDD = +5 V
± 5%, GND = 0 V, Ta = 0°C to +70°C)
*1: WAIT is asserted only when the write access conflicts with that of the network on reading the buffer memory
port (BMPR8).
*2: WAIT is asserted only when the write access conflicts with that of the network on reading the buffer memory
port (BMPR8).
This value will be 2.15
s when the bus write error occurs on reading the buffer memory port.
