TS68882
When connected as a peripheral processor, the TS68882 chip select (CS) decode is
system dependent. If the TS68000 is used as the main processor, the TS68882 CS
must be decoded in the supervisor or user data spaces. However, if the TS68010 is
used as the main processor, the MOVES instruction may be used to emulate any CPU
space access that the TS68020/co-processorTS68030 generates for co-processor com-
munications. Thus, the CS decode logic for such systems may be the same as in a
TS68020/TS68030 systems, such that the TS68882 will not use any part of the data
address spaces.
