Signal Naming Convention

The following conventions are used in describing the signals for Orin module:
Signal names use a mnemonic to represent the function of the signal. For example, I2S

interface #0 shift clock signal is represented as
signals are identified by an asterisk (*) after the signal name. For example,
indicates an active-low signal. Active-high signals do not have the (*) after the signal
names. For example,
identified as a pair with the same names that end with
respectively). For example,
The signal I/O type is represented as a code to indicate the operational characteristics of

the signal. The following table lists the I/O codes used in the signal description tables.
