The module contains a chaining direct memory access (DMA) engine that reduces the interrupt load on
the application processor, and reduces the total system bus bandwidth that must be dedicated to servicing
the USB interface requirements.
To reduce bus utilization by the USB even more, the module’s DMA does not have access to the CPU bus,
but instead accesses a dedicated memory that can be read/written by the CPU.
24.4
The module has three basic operating modes: Host, Peripheral (device), and OTG.
The mode of operation is selectable by software. In Host mode, the module supports Low, Full and High
speed USB. In Peripheral mode, only Full and High speed are supported.
24.5
This section contains detailed descriptions of the USB interface signals.
24.5.1
The On-Chip transceiver is a UTMI+ specification compliant transceiver. It supports High, Full, and Low
speed data transmission, in both Host and Device mode. In addition, it contains all necessary circuitry for
OTG specific functionality.
Note that the USB Controller does not support Low speed operation in device mode as per USB 2.0
specification.
24.5.2
The built-in PHY has its own on-chip oscillator and PLL to generate the USB serial clocks. The oscillator
needs an external 24 MHz crystal.
