Note: When a lower case “n” is used at the beginning of the signal name, it indicates that the signal
is active low. For example, nRST indicates that the reset signal is active low.
Note: The buffer type for each signal is indicated in the BUFFER TYPE column. A description of the
buffer types is provided in Section 2.2.
