The High-Speed Synchronous Serial Interface (SSC) supports full-duplex and
half-duplex synchronous communication. The serial clock signal can be generated by
the SSC internally (master mode), using its own 16-bit baud-rate generator, or can be
received from an external master (slave mode). Data width, shift direction, clock polarity
and phase are programmable. This allows communication with SPI-compatible devices
or devices using other synchronous serial interfaces.
Features:
• Master and slave mode operation
• Transmit and receive buffered
• Flexible data format
• Variable baud rate
• Compatible with Serial Peripheral Interface (SPI)
• Interrupt generation
Data Sheet
– Full-duplex or half-duplex operation
– Programmable number of data bits: 2 to 8 bits
– Programmable shift direction: LSB or MSB shift first
– Programmable clock polarity: idle low or high state for the shift clock
– Programmable clock/data phase: data shift with leading or trailing edge of the shift
– On a transmitter empty condition
– On a receiver full condition
– On an error condition (receive, phase, baud rate, transmit error)
