R/W Stop Bit Length
Selects one or two bits as the stop bit length in
asynchronous mode. This setting is used only in
asynchronous mode. It is ignored in synchronous mode
because no stop bits are added.
When receiving, only the first stop bit is checked,
regardless of the STOP bit setting. If the second stop
bit is 1, it is treated as a stop bit, but if the second stop
bit is 0, it is treated as the start bit of the next incoming
character.
0: One stop bit
When transmitting, a single 1-bit is added at the end
of each transmitted character.
1: Two stop bits
When transmitting, two 1 bits are added at the end of
each transmitted character.

R/W Select the internal clock source of the on-chip baud rate
generator. Four clock sources are available. Pφ, Pφ/4,
Pφ/16 and Pφ/64. For further information on the clock
source, bit rate register settings, and baud rate, see
section 15.3.8, Bit Rate Register (SCBRR).
