ESSI
The ESSI peripheral enables serial-port communication between the DSP core and external
devices including Codecs, DSP, microprocessors. The ESSI is capable of driving 12
programmable external pins which can be configured as GPIO ports C and D or ESSI pins.
The key features of the ESSI are:

EOC
The Salieri extended on-chip memory interface provides access to 40 kB of on-chip
memory. The Mozart core will treat this memory as if it were external. Access by off-chip
expansion bus masters is permitted. All accesses to the extended on-chip RAM are
controlled by the extended on-chip memory control register. This register determines which
combinations of the Address attribute pins should be interpreted as accesses to the 40 kB of
RAM.
8 bit parallel port "Full-duplex" dedicated host register bank
Dedicated Mozart™ core DSP register core bank.
Register banks map directly into Mozart X memory space

Independent receiver and transmitter
Synchronous or asynchronous channel modes synchronous. Receiver and transmitter
use same clock/sync asynchronous. Receiver and transmitter may use separate
clock/sync up to one transmitter enabled in asynchronous channel mode.
Up to three transmitters enabled in synchronous channel mode.
Normal mode. One word per period.
Network mode. Up to 32 words per period.
