ICP_FWD_LOCK_GRANT
This bit serves as an access lock bit controlling the access to the forwarding ICP buffer. A
read from this location returns the current lock status. When the
ICP_FWD_LOCK_GRANT reads back as ‘1’, the microprocessor is granted read access to
the buffer; further writes by the RIPP internal logic are prohibited. Otherwise RIPP has
control over the area.
ICP_FWD_LOCK_REQ
Writing ‘1’ to the register location requests the lock for microprocessor read access; while
writing ‘0’ releases the lock.
