Chip Identification
PIO Controllers
• Two-pin UART
• Debug Communication Channel Support
• Chip ID: 0x019607A0
• JTAG ID: 0x05B0C03F
• ARM926 TAP ID: 0x0792603F
• Five PIO Controllers, PIOA to PIOE, controlling a total of 160 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
– Debug Communication Channel (DCC) support
– Implemented features are 100% compatible with the standard Atmel USART
– Independent receiver and transmitter with a common programmable Baud Rate
– Even, Odd, Mark or Space Parity Generation
– Parity, Framing and Overrun Error Detection
– Automatic Echo, Local Loopback and Remote Loopback Channel Modes
– Support for two PDC channels with connection to receiver and transmitter
– Offers visibility of and interrupt trigger from COMMRX and COMMTX signals from
– PIOA has 32 I/O Lines
