With the misaligned character shown in
154 RT cycles at the point when the count of the transmitting device
is 9 bit times
The maximum percent difference between the receiver count and the
transmitter count of a slow 8-bit character with no errors is
For a 9-bit character, data sampling of the stop bit takes the receiver
10 bit times
With the misaligned character shown in
170 RT cycles at the point when the count of the transmitting device
is 10 bit times
The maximum percent difference between the receiver count and the
transmitter count of a slow 9-bit character with no errors is

misaligned without causing a noise error or a framing error. The fast
stop bit ends at RT10 instead of RT16 but is still there for the stop bit
data samples at RT8, RT9, and RT10.
For an 8-bit character, data sampling of the stop bit takes the receiver
9 bit times

shows how much a fast received character can be
16 RT cycles + 10 RT cycles = 154 RT cycles.
16 RT cycles + 10 RT cycles = 170 RT cycles.
16 RT cycles + 3 RT cycles = 147 RT cycles.
16 RT cycles + 3 RT cycles = 163 RT cycles.
