5. TEND Flag and TE Bit Processing: The TEND flag is set to 1 during transmission of the stop
bit of the last data. Consequently, if the TE bit is cleared to 0 immediately after setting of the
TEND flag has been confirmed, the stop bit will be in the process of transmission and will not be
transmitted normally. Therefore, the TE bit should not be cleared to 0 for at least 0.5 serial clock
cycles (or 1.5 cycles if two stop bits are used) after setting of the TEND flag is confirmed.
6. Receive Data Sampling Timing and Receive Margin: The SCIF operates on a base clock
with a frequency of 16 times the transfer rate. In reception, the SCIF synchronizes internally with
the fall of the start bit, which it samples on the base clock. Receive data is latched at the rising
edge of the eighth base clock pulse. The timing is shown in figure 16.13.
The receive margin in asynchronous mode can therefore be expressed as shown in equation 1.
Equation 1:
Where:
From equation 1, if F = 0 and D = 0.5, the receive margin is 46.875%, as given by equation 2.
