Synchronous Serial Interface (SSI) Signals

The SSI module uses the signals in this section.
Freescale Semiconductor
Table 2-12. I
Abbreviation
I2C_SCL Open-drain clock signal for the I
module when the bus is in the master mode or it becomes the clock
input when the I
I2C_SDA Open-drain signal that serves as the data input/output for the I
interface.

Abbreviation
CANTX Controller area network transmit data output.
CANRX Controller area network receive data input.
Abbreviation
QSPI_DOUT Provides the serial data from the QSPI and can be programmed to be
driven on the rising or falling edge of QSPI_CLK. Each byte is sent
msb first.
QSPI_DIN Provides the serial data to the QSPI and can be programmed to be
sampled on the rising or falling edge of QSPI_CLK. Each byte is
written to RAM lsb first.
QSPI_CLK Provides the serial clock from the QSPI. The polarity and phase of
QSPI_CLK are programmable. The output frequency is programmed
according to the following formula, in which n can be any value
between 1 and 255:
QSPI_CS[2:0] Provide QSPI peripheral chip selects that can be programmed to be
active high or low.
