Function
Data Bus
When operated in address/data
multiplex mode, this bus is used as a
multiplexed AD bus. The Address pins
are externally connected to the AD bus.
Address Bus (bits 6 ... 0 except bit 4)
When operated in address/data
multiplex mode, this bus is used as a
multiplexed AD bus. The Data pins are
externally connected to the AD bus.
Bit 4 of the address bus/ DMA
Acknowledge
In non-DMA mode DACK/A4 input pin
should be connected to A4 of the µP
address-bus.
In DMA mode A4 is internally
connected to ‘0’.
DMA Request for Receive Direction
May be configured to active high or
active low (the default is active high)
DMA Request for Transmit Direction
May be configured to active high or
active low (the default is active high)
