	  This is the port size used by the Host and EC to communicate over

	help
	  Workaround the issue documented in NPCX99nF errata rev1_2, No.3.10.
	  Enabling an eSPI channel during an eSPI transaction might
	  (with low probability) cause the eSPI_SIF module to transition to
	  a wrong state and therefore response with FATAL_ERROR on an incoming
	  transaction.

# The default value 'y' for the existing options if ESPI_NPCX is selected.
