NuMicro^™ M052/M054BN Data Sheet
6.5.2 Features
The I²C bus uses two wires (SDA and SCL) to transfer information between devices connected to
the bus. The main features of the bus are:
 Support Master and Slave mode
 Bidirectional data transfer between masters and slaves
 Multi-master bus (no central master)
 Arbitration between simultaneously transmitting masters without corruption of serial data
on the bus
 Serial clock synchronization allows devices with different bit rates to communicate via
one serial bus
 Serial clock synchronization can be used as a handshake mechanism to suspend and
resume serial transfer
 Built-in a 14-bit time-out counter will request the I²C interrupt if the I²C bus hangs up and
timer-out counter overflows.
 External pull-up are needed for high output
 Programmable clocks allow versatile rate control
 Supports 7-bit addressing mode
 I²C-bus controllers support multiple address recognition ( Four slave address with mask
option)
