AMCC Proprietary
Revision 1.27 - August 22, 2007
Preliminary Data Sheet
Loopback controls for isolating communications link faults
Break, parity, overrun, framing error simulation
OPB interface with optional DMA support
IIC Bus Interface
The Inter-Integrated Circuit (IIC) interface provides a Philips I
2
C
compatible interface operating up to 400kHz
either as a master, a slave, or both with a bootstrap controller (BSC) included. During chip reset, the bootstrap
controller can read configuration data from an IIC compatible memory device (e.g., EEPROM). This data can be
used to replace the default configuration settings provided by the chip.
Features include:
One IIC channel
Compliant with
Philips Semiconductors I
2
C Specification
, dated 1995
100 kHz or 400 kHz operation
8-bit data
10- or 7-bit address
Slave Transmit and Receive
Master Transmit and Receive
Multiple bus masters supported
Programmable as master, slave, or master/slave
Boot parameters read from IIC attached memory with IIC bootstrap controller
32-bit OPB slave interface
Serial Peripheral Interface (SPI/SCP)
The Serial Peripheral Interface (SPI) (also known as the Serial Communications Port or SCP) is a full-duplex,
synchronous, character-oriented (byte) port that allows the exchange of data with other serial devices. The SPI is a
master on the serial port supporting a 3-wire interface (receive, transmit, and clock), and is a slave on the OPB.
Features include:
One SPI/SCP channel, full duplex synchronous
SPI/SCP master
Up to 40 MHz
Programmable internal loopback capabilities
Multi-master protocol supported
Independent masking of all interrupts (master collision, transmit FIFO overflow, transmit FIFO empty, receive
FIFO full, receive FIFO underflow, receive FIFO overflow)
Dynamic control of serial bit rate of data transfer (serial-master mode only)
Data Item size for each data transfer under programmer control (4-to-16 bits)
Boot from SPI supported
32-bit OPB slave interface
