10.13 Chip Identification
10.14 PIO Controllers
6430DS–ATARM–28-Mar-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
