Description
Transmit End Interrupt Enable
When this bit is set to 1, a TEI interrupt request is
enabled. A TEI interrupt request can be cancelled by
reading 1 from the TDRE flag and then clearing the flag
to 0 in order to clear the TEND flag to 0, or by clearing
the TEIE bit to 0.
Clock Enable 1, 0 (for SCI_0, 1, and 4)
These bits select the clock source and SCK pin function.

Asynchronous mode
Clocked synchronous mode
The SCK pin functions as I/O port.
The clock with the same frequency as the bit rate is
output from the SCK pin.
The clock with a frequency 16 times the bit rate
should be input from the SCK pin.
The SCK pin functions as the clock input pin.
The SCK pin functions as the clock output pin.
