USB Registers
Two different kinds of registers are implemented in the USB module. The global registers (GEPIR,
EPSEL, ADROFF, USBVAL) describe the basic functionality of the complete USB module and can
be accessed via unique SFR addresses. For reduction of the number of SFR addresses which are
needed to control the USB module inside the C540U/C541U, device registers and endpoint
registers are mapped into an SFR address block of seven SFR addresses (C1H to C7H). The
endpoint specific functionality of the USB module is controlled via the device registers DCR,
DPWDR, DIER, DIRR and the frame number registers. An endpoint register set is available for each
endpoint (n=0..4) and describes the functionality of the selected endpoint.
Figure 14
explains the
structure of the USB module registers.
