• Chip Identifier (CHIPID) registers permit recognition of the device and its revision.
• JTAG ID: 0x05B2D03F
• Two-pin UART
• 3 PIO Controllers, PIOA, PIOB and PIOC (100-pin version only) controlling a maximum of 79
• Fully programmable through Set/Clear Registers
• Multiplexing of four peripheral functions per I/O Line
• 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
