This is the port size used by the Host and EC to communicate over
the shared memory region to return the ACPI response data. Please
notice the valid value in npcx ec series for this option is 8/16/32/

This is the port size used by the Host and EC to communicate over
the shared memory region to return the host command parameter data.

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.

EC can accept 1/2/4 bytes of Port 80 data written from the Host in an
eSPI transaction.
