Bit 2—Transmit End Interrupt Enable (TEIE): Bit 2 enables or disables the transmit end
interrupt (TEI) requested if there is no valid transmit data in TDR when the MSB is transmitted.

Note: * A TEI interrupt can be cleared by clearing the SSR bit TDRE to 0 and clearing the transmit
Bits 1 and 0—Clock Enable 1, 0 (CKE1, CKE0): Bits 1 and 0 select the clock source and enable
or disable clock output at pin SCK
pin SCK
Note that the CKE0 setting is valid only when operation is in asynchronous mode using an internal
clock (CKE1 = 0). This bit is invalid in synchronous mode or when using an external clock
(CKE1 = 1). In synchronous mode and in external clock mode, clear CKE0 to 0. After setting bits
CKE1 and CKE0, the operation mode must first be set in the serial mode register (SMR).
See table 10.9 in 10.4.3, Operation, for details on clock source selection.
