Note:
1. The symbols used for timing specifications herein follow the pattern of t(first two letters of functional block)(signal)(state) (reference)(state)
for inputs and t(first two letters of functional block)(reference)(state)(signal)(state) for outputs. For example, tTRDVKH symbolizes TBI
receive timing (TR) with respect to the time data input signals (D) reach the valid state (V) relative to the tTRX clock reference
(K) going to the high (H) state or setup time. Also, tTRDXKH symbolizes TBI receive timing (TR) with respect to the time data
input signals (D) went invalid (X) relative to the tTRX clock reference (K) going to the high (H) state. Note that, in general, the
clock reference symbol representation is based on three letters representing the clock of a particular functional. For example,
the subscript of tTRX represents the TBI (T) receive (RX) clock. For rise and fall times, the latter convention is used with the
appropriate letter: R (rise) or F (fall). For symbols representing skews, the subscript is skew (SK) followed by the clock that
is being skewed (TRX).
