8.6.1

HOST-TO-EC MAILBOX REGISTER

HOST_EC_MBOX[7:0]

If enabled, an interrupt to the EC marked by the EM_MBX bit in the GIRQ15 Source Register will be generated when-

ever the Host writes this register. The Host and the EC can read and write this register at offset 000h. The EC can also

read this register at offset 100h.

Writes of a 1 to any bit in this register by the EC to this register at offset 100h will cause the bit to be cleared. Writes of

a 0 to any bit have no effect.
