SPICT<TXMOD> bit.
when the UNIT-size data is loaded into the SPITD register where SPICT<TXE> = 1, or
when the SPICT<TXE> is set to 1 after loading one UNIT-size data into the SPITD register.
During the data transmission, it is prohibited to change the transmission mode from
Sequential to UNIT, or vice versa.

the TEND interrupt is generated upon completion of the transmission of the last UNIT
data.
SPICT<TXMOD> bit. The 32-byte FIFO is enabled in Sequential mode.
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
The transmit FIFO buffer is disabled in UNIT mode. The UNIT-mode transmission starts
In the UNIT-mode transmisison, 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:
Don’t touch to all other SFRs, TXE=1 and UNIT transmission will finish completely.
In case of using UNIT mode: TXMOD=0, there is one restriction.
