[Figure 3-1. USB-IK01 Function Block Diagram]
The USB-IK01 is largely divided into two parts as indicated by the dotted box (electrically
completely separated). First, it is the memory and I/O expansion part using EPLD (XC9536XL), and
the interface part that enables the EPLD program itself. Therefore, it is possible to change the
hardware configuration without the need for a separate EPLD programmer.
