SSP_SCLK is the serial bit clock used to control the timing of a transfer. SSP_SCLK can be generated
internally (Master mode) as defined by a control register bit internal to the IXP45X/IXP46X network
processors.
SSP_SFRM is the serial frame indicator that indicates the beginning and the end of a serialized data
word. The SSP_SFRM can be generated internally (Master mode) or taken from an external source
(Slave mode) as defined by a control register bit internal to the IXP45X/IXP46X network processors.
This signal may be active low or active high depending upon the mode of operation.
Please refer to the Intel
Manual for additional details.
SSP_TXD is the Transmit data (serial data out) serialized data line. Sample length is a function of the
selected serial data sample size.
SSP_RXD is the Receive data (serial data in) serialized data line. Sample length is a function of the
selected serial data sample size.
Should be pulled high through a 10-KΩ resistor when not being utilized in the system.
SSP_EXTCLK is an external clock which can be selected to replace the internal 3.6864 MHz clock. The
SSP_EXTCLK input is selected by setting various internal registers to appropriate values.
Should be pulled high through a 10-KΩ resistor when not being utilized in the system.
