Figure 6. R-C Circuit
The MAX II development board provides four test points to allow the
designer to analyze the timing of the MAX II device power-up and
configuration.
For more information on using the test points to analyze the MAX II
device power up and configuration, see the MAX II Development Kit
Getting Started User Guide.
Table 27
A prototype area consisting of an array of 120 0.1-inch holes is provided.
This area can be used to add custom components to the MAX II
development board. Connections to both the 3.3 V plane and ground
plane of the MAX II board are included. The silk-screen text on the board
indicates which holes are connected to which planes. All of the other
holes are not connected to anything on the board.
