this data sheet.
Programmable I/O Cells (PIC)
Each PIC contains two PIOs connected to their respective sysI/O buffers as shown in Figure 2-28. The PIO Block
supplies the output data (DO) and the tri-state control signal (TO) to the sysI/O buffer and receives input from the
buffer. Table 2-12 provides the PIO signal list.
