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

Description

Transmit end interrupt request (TEI) disabled

(initial value)

Transmit end interrupt request (TEI) enabled*

Note:

TEI can be released by clearing bit TDRE to 0 and clearing bit TEND to 0 in SSR, or by

clearing bit TEIE to 0.

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

3x pin.

The combination of CKE1 and CKE0 determines whether the SCK

3x 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 10.9 in 10.3.1, Overview.
