The SCI receiver operates asynchronously. An internal clock is necessary to synchronize with an incoming
data stream. The SCI baud rate generator produces a receive time sampling clock with a frequency 16
times that of the SCI baud rate. The SCI determines the position of bit boundaries from transitions within
the received waveform, and adjusts sampling points to the proper positions within the bit period.

clock speed is 1250 Kbaud.

The PT bit in SCCxR1 selects either even (PT = 0) or odd (PT = 1) parity. PT affects received and
transmitted data. The PE bit in SCCxR1 determines whether parity checking is enabled (PE = 1) or
disabled (PE = 0). When PE is set, the MSB of data in a frame (i.e., the bit preceding the stop bit) is used
for the parity function. For transmitted data, a parity bit is generated. For received data, the parity bit is
checked. When parity checking is enabled, the PF bit in the SCI status register (SCxSR) is set if a parity
error is detected.
Enabling parity affects the number of data bits in a frame, which can in turn affect frame size.
