All of the external memory accesses are performed by a particular on-chip External Bus
Controller (EBC). It can be programmed either to Single Chip Mode when no external
memory is required, or to one of four different external memory access modes

, which
are as follows:
– 16
…
24-bit Addresses, 16-bit Data, Demultiplexed

24-bit Addresses, 8-bit Data, Demultiplexed
In the demultiplexed bus modes, addresses are output on PORT1 and data is
input/output on PORT0 or P0L, respectively. In the multiplexed bus modes both
addresses and data use PORT0 for input/output. The high order address (segment) lines
use Port 4. The number of active segment address lines is selectable, restricting the
external address space to 8 Mbytes
…
64 Kbytes. This is required when interface lines
are assigned to Port 4.
Up to 4 external CS signals (3 windows plus default) can be generated in order to save
external glue logic. External modules can directly be connected to the common
address/data bus and their individual select lines.
Important timing characteristics of the external bus interface have been made
programmable (via registers TCONCSx/FCONCSx) to allow the user the adaption of a
wide range of different types of memories and external peripherals.
In addition, up to 4 independent address windows may be defined (via registers
ADDRSELx) which control the access to different resources with different bus
characteristics. These address windows are arranged hierarchically where window 4
overrides window 3, and window 2 overrides window 1. All accesses to locations not
covered by these 4 address windows are controlled by TCONCS0/FCONCS0. The
currently active window can generate a chip select signal.
The external bus timing is related to the rising edge of the reference clock output
CLKOUT. The external bus protocol is compatible with that of the standard C166 Family.
The EBC also controls accesses to resources connected to the on-chip LXBus. The
LXBus is an internal representation of the external bus and allows accessing integrated
peripherals and modules in the same way as external components.
External Bus Controller
1) Bus modes are switched dynamically if several address windows with different mode settings are used.
