without causing a noise error or a framing error. The fast stop bit ends at
RT10 instead of RT16 but is still sampled at RT8, RT9, and RT10.
For 8-bit data, sampling of the stop bit takes the receiver:
With the misaligned data shown in
154 RT cycles at the point when the count of the transmitting device is:
The maximum percent difference between the receiver count and the
transmitter count for fast 8-bit data with no errors is:
For 9-bit data, sampling of the stop bit takes the receiver:
With the misaligned data shown in
170 RT cycles at the point when the count of the transmitting device is:
The maximum percent difference between the receiver count and the
transmitter count for fast 9-bit data with no errors is:

16 RT cycles + 10 RT cycles = 154 RT cycles.
16 RT cycles + 10 RT cycles = 170 RT cycles.
