*1: READY is negated only when the read access is conflicted with that of the network on reading the buffer memory
port (BMR8).
This value would be 2.15
μ
s when the bus read error occurs on reading the buffer memory port.
*2: READY is negated only when the read access is conflicted with that of the network on reading the buffer memory
port (BMR8).
*3: Max time is 28 ns for normal read. Max time is 175 ns only when the read access is conflicted with that of the
network on reading the buffer memory port (BMR8).
This value would be 2.15
μ
s when the bus read error occurs on reading the buffer memory port.
