at 3 or more wait states of the C31, with more when the HOST is accessing it as well. The
HOST has priority during arbitration for a given cycle.
3.4 IP INTERFACE and PAGED MEMORY
The ID and IO space for the IPs are directly accessed based on the memory map below. IP
memory space is overlaid with the EPROM and FLASH space, and is controlled via the
register CTRL 1.
