15.1 Signal Name Conventions
The following conventions are used in describing the signals for Tegra:
 Signal names use a mnemonic to represent the function of the signal. For example,
Secure Digital Interface #3 Command signal is represented as
SDMMC_CMD, written in bold
to distinguish it from other text. All active-low 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 underscore-N (_N) after the signal names. For example,
SDMMC_CMD indicates an active-high signal. Differential signals are identified as a pair with
the same names that end with _P and _N or for USB 2.0, DP and DN (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.
