2.2.13 I2C

This device contains two I2C modules, which support up to 1 Mbits/s by dual buffer

features, and address match to wake MCU from the low power mode.

I2C modules support DMA transfer, and the interrupt condition can trigger DMA

request when DMA function is enabled.

The I2C modules have the following features:

• Support for system management bus (SMBus) Specification, version 2

• Software programmable for one of 64 different serial clock frequencies

• Software-selectable acknowledge bit

• Arbitration-lost interrupt with automatic mode switching from master to slave

• Calling address identification interrupt

• START and STOP signal generation and detection

• Repeated START signal generation and detection

• Acknowledge bit generation and detection

• Bus busy detection

• General call recognition

• 10-bit address extension

• Programmable input glitch filter

• Low power mode wakeup on slave address match

• Range slave address support

• DMA support

• Double buffering support to achieve higher baud rate

2.2.14

USB

This device contains one USB module which implements a USB2.0 full-speed

compliant peripheral and interfaces to the on-chip USBFS transceiver. It implements

keep-alive feature to avoid re-enumerating when exiting from low power modes and

enables HIRC48M to allow crystal-less USB operation.

The USBFS has the following features:

• USB 1.1 and 2.0 compatible FS device controller

• 16 bidirectional endpoints

• DMA or FIFO data stream interfaces

• Low-power consumption
