Input and Output Register Control per PIO Pair
Figure 11:
PIO pins are grouped into pairs for synchronous control. Registers within pairs of PIO pins share common input
clock, output clock, and I/O clock enable control signals, as illustrated in
are removed from the drawing for clarity.
The INCLK clock signal only controls the input flip-flops within the PIO pair.
The OUTCLK clock signal controls the output flip-flops and the output-enable flip-flops within the PIO pair.
If desired in the iCE65 application, the INCLK and OUTCLK signals can be connected together.
The IOENA clock-enable input, if used, enables all registers in the PIO pair, as shown in
registers are always enabled.
The pairing of PIO pairs is most evident in the tables in

PIO Pairs Share Clock and Clock Enable Controls (only registered paths shown for clarity)
Before laying out your printed-circuit board, run the design through the iCEcube development software to
verify that your selected pinout complies with these I/O register pairing requirements. See
