Table 10-2.
• Two-pin UART
• Up to 6 PIO Controllers, PIOA, PIOB, PIOC, PIOD, PIOE and PIOF controlling a maximum of
• Each PIO Controller controls up to 32 programmable I/O Lines
• 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
167 I/O Lines
– 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
– Input change, rising edge, falling edge, low level and level interrupt
– Debouncing and Glitch filter
– Multi-drive option enables driving in open drain
– Programmable pull-up on each I/O line
– Pin data status register, supplies visibility of the level on the pin at any time
