without causing a noise error or a framing error. The slow stop bit begins
at RT8 instead of RT1 but arrives in time for the stop bit data samples 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 slow 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 slow 9-bit data with no errors is:

shows how much a slow received frame can be misaligned
16 RT cycles + 10 RT cycles = 154 RT cycles.
16 RT cycles + 3 RT cycles = 147 RT cycles.
16 RT cycles + 10 RT cycles = 170 RT cycles.
16 RT cycles + 3 RT cycles = 163 RT cycles.
