Registers
The ML9620 allocates an address space of 256 bytes.
The registers are organized as 8 bits regisers.
Two sets
of interface registers are directly accessed from external MCU.
Message objects in Message RAM is accessable through the two sets of interface registers (IF1 and IF2) which
buffer data to be transferred to and from the message RAM, avoiding conflicts between MCU accesses and
message reception/transmission.
