Master/Slave.
Arbitration is handled between simultaneously transmitting masters without corruption
of serial data on the bus.
Programmable clock allows adjustment of I
Data transfer is bidirectional between masters and slaves.
Serial clock synchronization allows devices with different bit rates to communicate via
one serial bus.
Serial clock synchronization is used as a handshake mechanism to suspend and
resume serial transfer.
Supports Fast-mode Plus.
Optional recognition of up to four distinct slave addresses.
