Overview
All input and output signals pass through the GPIO (General Purpose Input and Output) module.
The GPIO module consists of a Look-Up Table (LUT – Cross-Point Switch), 2 Pulse Generators
and a 12-bit counter. In the LUT, the relationship between inputs, counters and outputs is
governed by internal register set-up.
