This LSI incorporates a USB function module complying with USB standard version 1.1. Figure
14.1 shows the block diagram of the USB.
14.1
• USB standard version 2.0 full speed mode (12 Mbps) support
• Bus-powered mode or self-powered mode is selectable via the USB specific pin (UBPM)
• On-chip PLL circuit to generate the USB operation clock (24 MHz × 2 = 48 MHz, 16 MHz × 3
• On-chip bus transceiver
• Standard commands are processed automatically by hardware
• Current Configuration value can be checked by Set_Configuration interrupt
• Three transfer modes supported (Control, Bulk, Interrupt)
• Configuration of four endpoints; EP0, EP1, EP2, and EP3
• 16 kinds of interrupts
• DMA transfer interface
• 8-bit bus (3 cycle access timing) connected to the external bus interface

⎯ Only Set_Descriptor, Get_Descriptor, Class/VendorCommand, and SynchFrame
⎯ Suspend/resume interrupt source can be assigned for IRQ6
⎯ Each interrupt source except the suspend/resume interrupt source can be assigned for
⎯ DMA transfer is enabled for the Bulk transfer data of EP1 and EP2
⎯ Internal registers are addressed to a part of area 6 of external address (H'C00000 to
⎯ Address H'C00100 to H'DFFFFF is for USB reserved area and thus access prohibited.
