Function
SYSTEM DATA BUS
These pins are used as data buses for data
exchange between the host system and the
MB86967. They are also used for DMA transfer. In
the 8-bit bus mode (bit 5 of DLCR6 = 1), only the 8
lower bits (SD0 to SD7) are used.
These pins are used for input of system address
signals for selecting LAN controller registers.
ISU This pin is used for input of hardware reset signals.

ISD This pin is used for input of signals indicating that the
DMA controller controls the system bus.
ID
This pin is used for input of signals indicating the end
of DMA transfer between the buffer memory and host
system. At input of EOP the next BREQ is not output
and the handshaking cycle is terminated.
ID
This pin is used for input of signals indicating that the
addresses of SA0 to SA9 are determined.
IU
This pin is used for controlling byte/word transfer. In
the 16-bit data bus mode (bit 5 (SB/SW) of DLCR6 =
0), this pin, together with SA0, controls word transfer
and the transfer of upper and lower bytes on the data
bus.
