Chip Identification
PIO Controllers
• Debug Communication Channel Support
• Chip ID: 83770904 (0x1000 0011 0111 0111 0000 1001 0000 0100). This value is stored in
• JTAG ID: unique for each CAP7 personalization.
• Two PIO Controllers (PIOA and PIOB) included.
• Each PIO Controller controls up to 32 programmable I/O Lines
• Fully programmable through Set/Clear Registers
• For each I/O Line (whether assigned to a peripheral or used as general purpose I/O)
• Synchronous output, provides Set and Clear of several I/O lines in a single write
• PIOA has multiplexing of two peripheral functions per I/O Line (see section
• PIOB multiplexing is controlled by the FPGA Interface (see section
the Chip ID Register (DBGU_CIDR) in the Debug Unit. The last 5 bits of the register are
reserved for a chip version number.
