Notes:
1. The symbols used for timing specifications herein follow the pattern of t
2. This parameter is dependent on the csb_clk speed (that is, for a csb_clk of 267 MHz, the maximum frequency is

outputs (D) are invalid (X) or data hold time. Also, t
to the time data input signals (D) reach the valid state (V) relative to the t
(H) state or setup time. For rise and fall times, the latter convention is used with the appropriate letter: R (rise) or F
(fall).
