21.18.17 UEDATX – USB Data Endpoint Register
21.18.18 UEBCLX – USB Endpoint Byte Count Register
7799D–AVR–11/10
• Bit 3 – RXSTPE: Received SETUP Interrupt Enable Flag
Writing this bit to one enables interrupt on RXSTPI flag. A receiveD setup interrupt will be gener-
ated only if the RXSTPE bit is set to one, the Global Interrupt Flag in SREG is written to one, and
the RXSTPI is set.
• Bit 2 – RXOUTE: Received OUT Data Interrupt Enable Flag
Writing this bit to one enables interrupt on RXOUTI flag. A receiveD OUT interrupt will be gener-
ated only if the RXOUTE bit is set to one, the Global Interrupt Flag in SREG is written to one,
and the RXOUTI is set.
• Bit 1 – STALLEDE: Stalled Interrupt Enable Flag
Writing this bit to one enables interrupt on STALLEDI flag. A sent STALL interrupt will be gener-
ated only if the STALLEDE bit is set to one, the Global Interrupt Flag in SREG is written to one,
and the STALLEDI is set.
• Bit 0 – TXINE: Transmitter Ready Interrupt Enable Flag
Writing this bit to one enables interrupt on TXINI flag. A transmitter ready interrupt will be gener-
ated only if the TXINE bit is set to one, the Global Interrupt Flag in SREG is written to one, and
the TXINI is set.
• Bits 7:0 – DAT[7:0]: Data Bits
The USB Data Endpoint register is a read/write register used for data transfer between the Reg-
ister File and the USB device controller. Writing to the register pushes the data byte into the
current bank of the selected endpoint. Reading the register pops extracts one data byte from the
current bank of the selected endpoint.
• Bits 7:0 – BYCT[7:0]:Byte Count Bits
This register is read only. Its content is updated by the USB controller.
This register contains the number of byte currently loaded into the current bank of the selected
endpoint. The content of this register is incremented after each write access to the endpoint data
register.
