The High-Speed Synchronous Serial Interfaces

The High-Speed Synchronous Serial Interfaces
The INCA-D comprises two High-Speed Synchronous Serial Interfaces SSC0 and
SSC1. These interfaces provide flexible high-speed serial communication between the
INCA-D and other microcontrollers, microprocessors or external peripherals.
The SSCs support full-duplex and half-duplex synchronous communication up to 12.5
MBaud. The serial clock signals can be generated by the SSCs itself (master mode) or
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. Transmission and reception of data is double-buffered. A 16-bit baud rate
generator provides each of the the SSC with a separate serial clock signal.
The high-speed synchronous serial interfaces can be configured in a very flexible way,
so they can be used with other synchronous serial interfaces (eg. the ASC in
synchronous mode), serve for master/slave or multimaster interconnections or operate
compatible with the popular SPI interface. So they can be used to communicate with shift
registers (IO expansion), peripherals (eg. EEPROMs etc.) or other controllers
(networking). The SSCs support half-duplex and full-duplex communication. Data is
transmitted or received for SSC0 on pins MTSR0/P3.9 (Master Transmit / Slave
Receive) and MRST0/P3.8 (Master Receive / Slave Transmit) and for SSC1 on the pins
MTSR1/P3.1 and MRST1/P3.0 respectively. The clock signals are output or input on pin
SCLK0/P3.13 or SCLK1/P3.2 respectively. These pins are alternate functions of Port 3
pins.
Figure 16-1 and Figure 16-2 give an overview about the used registers to control the
two SSCs.
