Full-speed emulation of standard I
Receiving commands to perform user-defined operations such as IAP
Three user configurable independent slave addresses can be individually enabled
2x 256 bytes and 1x 128 bytes buffers with fixed addresses in RAM
7-bit addressing
DMA transfer to/from I
Standard (transfers 256 bytes at up to 100 kHz)
Fast mode (transfers 256 bytes at up to 400 kHz)
Transfer error detection and handling
3 interrupt flags per address for maximum flexibility
Two interrupt request lines (one for Slaves 1 and 2, the other for Slave 3)
