following sections. Some operating modes can be defined using PSDsoft Express, and
some by the 8032 writing to the csiop registers at run-time, and some require both. For
example, PLD I/O, Latched Address Out, and Peripheral I/O modes must be defined in
PSDsoft Express and programmed into the device using JTAG, but an additional step must
happen at run-time to activate Latched Address Out mode and Peripheral I/O mode, but not
needed for PLD I/O. In another example, MCU I/O mode is controlled completely by the
8032 at run-time and only a simple pin name declaration is needed in PSDsoft Express for
documentation.
