18.3.1.4
The eSPI command register (SPCOM), shown in
the new frame.
After SPCOM has been written to initiate the first transaction after startup, commands can be executed
only after SPIE[DON] is set. Otherwise they are ignored.

If (RXSKIP != 0)—Number of characters skipped for reception from frame start.
Non-zero values of RxSKIP force the eSPI to half-duplex mode, and therefore this causes
TRANLEN–RxSKIP characters to be skipped for transmission.
RXSKIP is useful for reads of SPI Flash memories where the first valid read data is received several
characters after the transmission begins (after the eSPI has transmitted an instruction opcode and
address).
Note: If TO=1 RxSKIP is ignored.
If RXSKIP=0 and TO=0, the eSPI changes to full duplex mode.
