USB Module
Two different kinds of registers are implemented in the USB module.
1.) The global registers and the device registers describe the basic functionality of the
complete USB module and can be accessed via unique XBUS-SFR addresses. These
are the
• GEPIR (Global Endpoint Interrupt Request Register)
• GESR (Global Endpoint Stall Register)
• CIAR (Configuration Request Register)
• CIARI (Configuration Request Interrupt Register)
• CIARIE (Configuration Request Interrupt Enable Register)
• DCR (Device Control Register)
• DPWDR (Device Power Down Register)
• DIER (Device Interrupt Enable Register)
• DIRR (Device Interrupt Request Register)
• DSSR (Device Setup and Status Register)
• FNRH, FNRL (Frame Number High/Low Registers)
• DGSR (Device Get Status Register)
• IGSR (Interface Get Status Register)
• IFCSEL (Interface Select Register)
• ESTR (Enable Setup Token)
2.) The endpoint specific functionality of the USB module is controlled via an individual
set of registers for each of the 16 endpoints (n=0-15):
• EGSRn (Endpoint Get Status Register n)
• EPIEn (Endpoint Interrupt Enable Register n)
• EPIRn (Endpoint Interrupt Request Register n)
• EPBCn (Endpoint Buffer Control Register n)
• EPBSn (Endpoint Buffer Status Register n)
• EPBAn (Endpoint Base Address Register n)
• EPLENn (Endpoint Buffer Length Register n)
• ADROFFn (Address Offset Register n)
• USBVALn (USB Data Register n)
Standard Command Registers
The Set_Configuration and Set_Interface standard device commands are handled by
the UDC and are transparent to the firmware. They appear at the end of the enumeration
sequence, which can be detected by the first normal data transfer via USB.
