Bit Bit Name Initial Value R/W Description
2 TEIE 0 R/W Transmit End Interrupt Enable
When this bit is set to 1, TEI interrupt request is
enabled. TEI cancellation can be performed by
reading 1 from the TDRE flag in SSR, then clearing
it to 0 and clearing the TEND flag to 0, or by
clearing the TEIE bit to 0.

Clock Enable 1 and 0
Selects the clock source and SCK pin function.
Asynchronous mode
00: On-chip baud rate generator
SCK pin functions as I/O port
01: On-chip baud rate generator
(Outputs a clock of the same frequency as the
bit rate from the SCK pin.)
1×: External clock
(Inputs a clock with a frequency 16 times the bit
rate from the SCK pin.)
Clocked synchronous mode
0×: Internal clock (SCK pin functions as clock
output)
1×: External clock (SCK pin functions as clock
input)
Legend: ×: Don’t care
