Notes:

1. The symbols used for timing specifications 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, tGRDVKH symbolizes GMII

receive timing (GR) with respect to the time data input signals (D) reaching the valid state (V) relative to the tRX clock

reference (K) going to the high state (H) or setup time. Also, tGRDXKL symbolizes GMII receive timing (GR) with respect to

the time data input signals (D) went invalid (X) relative to the tGRX clock reference (K) going to the low (L) state or hold time.

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 tGRX represents the GMII (G) receive (RX) clock. For rise and fall times,

the latter convention is used with the appropriate letter: R (rise) or F (fall).

2. In rev. 2.0 silicon, due to errata, tGRDXKH minimum is 0.5 which is not compliant with the standard. Refer to Errata

QE_ENET18 in Chip Errata for the MPC8360E, Rev. 1.
