The Atmel Two-wire Slave Interface (TWIS) interconnects components on a unique two-wire
bus, made up of one clock line and one data line with speeds of up to 400 kbit/s, based on a
byte-oriented transfer format. It can be used with any Atmel Two-wire Interface bus, I²C, or
SMBus-compatible master. The TWIS is always a bus slave and can transfer sequential or sin-
gle bytes.
Below,
compatible device.
Table 28-1.
Note:
I²C
Standard-mode (100 kbit/s)
Fast-mode (400 kbit/s)
7 or 10 bits Slave Addressing
START BYTE
Repeated Start (Sr) Condition
ACK and NAK Management
Slope control and input filtering (Fast mode)
Clock stretching
Compatible with I
Compatible with SMBus standard
Compatible with PMBus
DMA interface for reducing CPU load
Arbitrary transfer lengths, including 0 data bytes
Optional clock stretching if transmit or receive buffers not ready for data transfer
32-bit Peripheral Bus interface for configuration of the interface
– Transfer speeds of 100 and 400 kbit/s
– 7 and 10-bit and General Call addressing
– Hardware Packet Error Checking (CRC) generation and verification with ACK response
– SMBALERT interface
– 25 ms clock low timeout delay
– 25 ms slave cumulative clock low extend time
