6 0 Operation of DP83907
This is the type of cycle used to read from a register or in 8-bit mode from a data transfer port These accesses are entirely
asynchronous with the DP83907 responding when it decodes the correct address on SA0-9 and an IORD If AEN is high the
cycle will be ignored CHRDY is deasserted if the DP83907 is not ready to respond and asserted when ready If it is ready
immediately CHRDY is not deasserted The data will always appear on SD0-7
