Notes:
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, tMDKHDX symbolizes
management data timing (MD) for the time tMDC from clock reference (K) high (H) until data outputs (D) are invalid (X) or
data hold time. Also, tMDDVKH symbolizes management data timing (MD) with respect to the time data input signals (D) reach
the valid state (V) relative to the tMDC clock reference (K) going to the high (H) state or setup time. For rise and fall times,
the latter convention is used with the appropriate letter: R (rise) or F (fall).
2. This parameter is dependent on the system clock speed.
3. Guaranteed by design.
4. tplb_clk is the platform (CSB) clock divided according to the SCCR[TSEC1CM].
