Note

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, tUSIXKH symbolizes USB timing

(USB) for the input (I) to go invalid (X) with respect to the time the USB clock reference (K) goes high (H). Also, tUSKHOX

symbolizes us timing (USB) for the USB clock reference (K) to go high (H), with respect to the output (O) going invalid (X) or

output hold time.
