LPC11U6x
32-bit ARM Cortex-M0+ microcontroller
8.18.1 Features
• One I
2
C-interface (I2C0) is an I
2
C-bus compliant interface with open-drain pins. The
I
2
C-bus interface supports Fast-mode Plus with bit rates up to 1 Mbit/s.
• One I
2
C-interface (I2C1) uses standard digital pins. The I
2
C-bus interface supports bit
rates up to 400 kbit/s.
• Easy to configure as master, slave, or master/slave.
• Programmable clocks allow versatile rate control.
• 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.
• The I
2
C-bus can be used for test and diagnostic purposes.
• The I
2
C-bus controller supports multiple address recognition and a bus monitor mode.
8.19 Timer/PWM subsystem
Four standard timers and two state configurable timers can be combined to create
multiple PWM outputs using the match outputs and the match registers for each timer.
Each timer can create multiple PWM outputs with its own time base.
