The High-Speed Serial (HSS) transmit frame signal can be configured as an input
or an output to allow an external source to be synchronized with the transmitted
data. Often known as a Frame Sync signal. Configured as an input upon reset.
Should be pulled high through a 10-kΩ resistor when not being used in the
system.
Transmit data out. Open-drain output.
Must be pulled up with a 10-kΩ resistor to V
The High-Speed Serial (HSS) transmit clock signal can be configured as an input
or an output. The clock can be a frequency ranging from 512 KHz to 8.192 MHz.
Used to clock out the transmitted data. Configured as an input upon reset.
Frame sync and Data can be selected to be generated on the rising or falling
edge of the transmit clock.
Should be pulled high through a 10-kΩ resistor when not being used in the
system.
The High-Speed Serial (HSS) receive frame signal can be configured as an input
or an output to allow an external source to be synchronized with the received
data. Often known as a Frame Sync signal. Configured as an input upon reset.
Should be pulled high through a 10-kΩ resistor when not being used in the
system.
Receive data input. Can be sampled on the rising or falling edge of the receive
clock.
Should be pulled high through a 10-kΩ resistor when not being used in the
system.
The High-Speed Serial (HSS) receive clock signal can be configured as an input
or an output. The clock can be from 512 KHz to 8.192 MHz. Used to sample the
received data. Configured as an input upon reset.
Should be pulled high through a 10-kΩ resistor when not being used in the
system.
The High-Speed Serial (HSS) transmit frame signal can be configured as an input
or an output to allow an external source become synchronized with the
transmitted data. Often known as a Frame Sync signal. Configured as an input
upon reset.
Should be pulled high through a 10-kΩ resistor when not being used in the
system.
Transmit data out. Open-drain output.
