Description
Core
Host Circular Buffer Write Window Field
(H_CB_WWF): This bit field is for host to write into its
circular buffer. The host's circular buffer is located at the
ME subsystem address specified in the Host CB Base
Address register. This field is write only, reads will return
arbitrary data. Writes to this register will increment the
H_CBWP as long as ME_RDY is 1. When ME_RDY is 0,
writes to this register have no effect and are not delivered
to the H_CB, nor is H_CBWP incremented.
