Serial Peripheral Interface
19.4.1.4
The SPI command register (SPCOM), shown in
Table 19-7
19.4.1.5
SPITD holds the character to be transmitted. The number of bits in each character is specified by
SPMODE[LEN]. Each time SPIE[NF] is set, the core can write another character of data to SPITD, if there
is no error indication in the SPIE. At the end of the frame the core should set SPCOM[LST] and prepare
the last character of data.

Reserved, should be cleared.
This bit represents the last character. Should be set before the last character is written to the SPITD. This
results in SPIE[LT] being set when the character is fully transmitted and by that gives indication about the
frame being fully transmitted.
0 This character is not the last character of the frame
1 This character is the last character of the frame
Reserved, should be cleared.
These bits are the data to be sent.
