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, t
USIXKH
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, t
USKHOX
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.

Oversample rate 16 — 2
Notes:
1. Actual attainable baud rate is limited by the latency of interrupt processing.
2. The middle of a start bit is detected as the 8

sampled 0 after the 1-to-0 transition of the start bit. Subsequent bit values are
sampled each 16
th
sample.
