Input signal. This signal is double signed by LAN91C111 to
determine access to the register of LAN91C111.
Input signal. Used by LAN91C111 to select of the internal register.
Input signal. Used for approval of double signing of the address. The
address can be double signed only when AEN is in the low state.
Input signal. Used to determine the register being accessed and the
access width while accessing the register of LAN91C111. When
nDATACS is in the low state (burst accessing), nBE0 to nBE3 are
ignored because 32-bit transmission is assumed.
