The tPad comes with a bus controller using the Max II EPM240 that allows user to access the touch
screen module through the HSMC connector. This section describes its structure in block diagram
form and its capabilities.
Bus Controller Introduction
The bus controller provides level shifting functionality from 2.5V (HSMC) to 3.3V domains.
