Naming Conventions

Input and output ports of the RocketIO transceiver primitives are denoted in upper-case
letters. Attributes of the RocketIO transceiver are denoted in upper-case letters with
underscores. Trailing numbers in primitive names denote the byte width of the data path.
These values are preset and not modifiable. When assumed to be the same frequency,
RXUSRCLK and TXUSRCLK are referred to as USRCLK and can be used interchangeably.
This also holds true for RXUSRCLK2, TXUSRCLK2, and USRCLK2.
Comma Definition
A comma is a "K" character used by the transceiver to align the serial data on a
byte/half-word boundary (depending on the protocol used), so that the serial data is
correctly decoded into parallel data.
