Preliminary
GENERAL DESCRIPTION
The ML60852 is a general purpose Universal Serial Bus (USB) device controller.
The ML60852 provde a USB serial interface engine, USB transceiver, FIFOs, control/status registers, application
interface circuit, and oscillation circuit thereby easily realizing a USB system. The ML60852 supports four types
of data transfer such as control transfer, bulk transfer, interrupt transfer and isochronous transfer, and also supports
five or six endpoints.
