how can we send binary data on two different pins simultaneously on both the rising edge and falling edge of dclk whose speed can be 1MHz on stm32f4?

PCA is managed by a full-duplex serial interface. A typical data frame is defined bya burst of 8 DCLK pulses followed by an assertion of a DLOAD pulse (these lines are driven by the host printing system.). During each frame, 32 bits of control or pri...
