SAM3S Summary

10.14 UART

•Two-pin UART

– Implemented features are 100% compatible with the standard Atmel USART

– Independent receiver and transmitter with a common programmable Baud Rate

Generator

– 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

10.15 PIO Controllers

• 3 PIO Controllers, PIOA, PIOB and PIOC (100-pin version only) controlling a maximum of 79

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)

– 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 or pull-down on each I/O line

– Pin data status register, supplies visibility of the level on the pin at any time

• Synchronous output, provides Set and Clear of several I/O lines in a single write
