Bit 2 Transmit End Interrupt Enable (TEIE): Bit 2 selects enabling or disabling of the
transmit end interrupt request (TEI) if there is no valid transmit data in TDR when MSB data is to
be sent.
Bit 2: TEIE

Note:
Bits 1 and 0 Clock Enable 1 and 0 (CKE1, CKE0): Bits 1 and 0 select the clock source and
enabling or disabling of clock output from the SCK
pin functions as an I/O port, a clock output pin, or a clock input pin.
The CKE0 bit setting is only valid in case of internal clock operation (CKE1 = 0) in asynchronous
mode. In synchronous mode, or when external clock operation is used (CKE1 = 1), bit CKE0
should be cleared to 0.
After setting bits CKE1 and CKE0, set the operating mode in the serial mode register (SMR).
For details on clock source selection, see table 10.10 in 10.3.3, Operation.
Bit 1: CKE1
