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, tTDMIVKH symbolizes TDM
timing (DM) with respect to the time the input signals (I) reach the valid state (V) relative to the TDM Clock, tTC, reference (K)
going to the high (H) state or setup time. Also, output signals (O), hold (X).
2. Output values are based on 30 pF capacitive load.
3. Inputs are referenced to the sampling that the TDM is programmed to use. Outputs are referenced to the programming edge
they are programmed to use. Use of the rising edge or falling edge as a reference is programmable. TDMxTCK and TDMxRCK
are shown using the rising edge.
