1.9.3 ESSI
The DSP56311 provides two independent and identical ESSIs. Each ESSI has a full-duplex serial
port for communication with a variety of serial devices, including one or more industry-standard
codecs, other DSPs, microprocessors, and peripherals that implement the Freescale SPI. The
ESSI consists of independent transmitter and receiver sections and a common ESSI clock
generator. ESSI capabilities include the following:
Independent (asynchronous) or shared (synchronous) transmit and receive sections with
separate or shared internal/external clocks and frame syncs
Normal mode operation using frame sync
Network mode operation with as many as 32 time slots
Programmable word length (8, 12, or 16 bits)
Program options for frame synchronization and clock generation
One receiver and three transmitters per ESSI
1.9.4 SCI
The SCI provides a full-duplex port for serial communication with other DSPs, microprocessors,
or peripherals such as modems. The SCI interfaces without additional logic to peripherals that
use TTL-level signals. With a small amount of additional logic, the SCI can connect to peripheral
interfaces that have non-TTL level signals, such as the RS-232C, RS-422, etc. This interface uses
three dedicated signals: transmit data, receive data, and SCI serial clock. It supports
industry-standard asynchronous bit rates and protocols, as well as high-speed synchronous data
transmission (up to 12.5 Mbps for a 100 MHz clock). SCI asynchronous protocols include a
multidrop mode for master/slave operation with wakeup on idle line and wakeup on address bit
capability. This mode allows the DSP56311 to share a single serial line efficiently with other
peripherals.
Separate SCI transmit and receive sections can operate asynchronously with respect to each
other. A programmable baud-rate generator provides the transmit and receive clocks. An enable
vector and an interrupt vector allow the baud-rate generator to function as a general-purpose
timer when the SCI is not using it or when the interrupt timing is the same as that used by the
SCI.
