17.1 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 I2S0_SCK. All active-low single-ended
signals are identified by an asterisk (*) after the signal name. For example, SYS_RESET*
indicates an active-low signal. Active-high signals do not have the (*) after the signal
names. For example, I2S0_FS indicates an active-high signal. Differential signals are
identified as a pair with the same names that end with _P and _N (for positive and negative,
respectively). For example, CSI_0_D0_P and CSI_0_D0_N indicate a differential signal pair.
 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.
