Otherwise, the TEMP interrupt is not properly generated.
sequentially when SPICT<TXE> = “1”. The transmission in this mode can also be started
by setting the SPICT<TXE> bit to “1” after writing the transmit data into the transmit
FIFO. The transmit data is transmitted in the same order as they were written into the
FIFO.
Therefore, the Sequential-mode transmission continues as long as the transmit FIFO (32
bytes) has any valid data. During the data transmission, it is prohibited to change the
transmission mode from Sequential to UNIT, or vice versa.
Differences Between the UNIT-mode and Sequential-mode transmissions
The UNIT mode for the data transmission can be selected by writing a “0” to the
The transmit FIFO buffer is disabled in UNIT mode. The UNIT-mode transmission starts
In the UNIT-mode transmission, the TEMP interrupt is generated when the transmit
The Sequential mode for the data transmission can be selected by writing a “1” to the
In this mode, the data writes to the transmit FIFO must be performed in 16-byte units.
In the Sequential-mode transmission, transmit data written into the SPITD is loaded
This mode of transmission keeps transmitting data as long as the transmit data exists.

Important Note:
When the SPICT<TEX> bit is set to “1”, the state of any bits must not be changed
When in UNIT mode (TXMOD = “0”), the following restriction is imposed on the
