Type
Intel/Motorola interface address bus. Can
be used as a GPI.
Intel/Motorola interface data bus, low bits
Intel/Motorola interface data bus, high bits.
Can be used as a GPIO if an 8 bit CPU
Interface is used.
Master Clock
that is multiplied to generate fast_clk.
General Reset
Direct Access Select. '1' selects the direct
access space. '0' selects the indirection
registers contained in the CPU interface.
This pin can be connected to a[15] of an
address bus but does not behave as an
address pin.
Intel/Motorola interface chip select
Intel/Motorola interface address latch
enable
Intel write or Motorola read/write
Intel read or Motorola data strobe
Intel/Motorola interface ready/data
acknowledge. This pin is active high for
Intel (rdy) and active low for Motorola
(ndtack).
CPU Interface Mode Select Bit 0. The
CPU Interface Mode Select bits must be
hardwired.
CPU Interface Mode Select Bit 1.
CPU Interface Mode Select Bit 2.
CPU Interface Mode Select Bit 3.
