Bit 2—Transmit-End Interrupt Enable (TEIE): This bit enables or disables the TSR-empty
interrupt (TEI) requested when the transmit-end bit (TEND) in the serial status register (SSR) is set
to "1."
Bit 2
TEIE Description
0 The TSR-empty interrupt request (TEI) is disabled.
1 The TSR-empty interrupt request (TEI) is enabled.
Bit 1—Clock Enable 1 (CKE1): This bit selects the internal or external clock source for the baud
rate generator. When the external clock source is selected, the SCK pin is automatically used for
input of the external clock signal.
Bit 1
CKE1 Description
0 Internal clock source.
When C/A = "1," the serial clock signal is output at the SCK pin.
When C/A = "0," output depends on the CKE0 bit.
1 External clock source. The SCK pin is used for input.
Bit 0—Clock Enable 0 (CKE0): When an internal clock source is used in asynchronous mode,
this bit enables or disables serial clock output at the SCK pin.
This bit is ignored when the external clock is selected, or when synchronous mode is selected.
For further information on the communication format and clock source selection, see table 8-7 in
section 8.3, "Operation."
Bit 0
CKE0 Description
0 The SCK pin is not used by the SCI (and is available as
a general-purpose I/O port).
1 The SCK pin is used for serial clock output.
