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