Note 1: When CPU finished current Read or Write operation, it can do next Read or Write operation even the
ARDY is low. During Read or Write operation if the ADRY is low, the CPU has to keep the RDN/WRN
low until the ARDY returns to high.
Note 2: In order to speed up the ARDY low time to 40 ns, user has to use the turbo software driver which is only
supported in the A6 device. Please refer to the “KSZ88xx Programmer's Guide” for detail.
