SAM3S8/SD8 Summary
10.13 Chip Identification
Chip Identifier (CHIPID) registers permit recognition of the device and its revision.
JTAG ID: 0x05B2D03F
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
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)
– Input change interrupt
– Programmable Glitch filter
– Programmable debouncing 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
– Additional interrupt modes on a programmable event: rising edge, falling edge, low
level or high level
