10.13 Chip Identification
10.14 PIO Controllers
6430ES–ATARM–22-Aug-11
Table 10-1.
Table 10-2.
• Chip Identifier (CHIPID) registers permit recognition of the device and its revision.
• JTAG ID: 0x0582A03F
• JTAG ID: 0x0582A03F
• 3 PIO Controllers, PIOA, PIOB, and PIOC, controlling a maximum of 96 I/O Lines
• Each PIO Controller controls up to 32 programmable I/O Lines
• Fully programmable through Set/Clear Registers
• Multiplexing of two 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

SAM3U1E (Rev A)
– PIOA has 32 I/O Lines
– PIOB has 32 I/O Lines
– PIOC has 32 I/O Lines
– Input change, rising edge, falling edge, low level and level interrupt
– Debouncing and Glitch filter
– Multi-drive option enables driving in open drain
