CHAPTER 22 USB FUNCTION CONTROLLER (USBF)
(11) UF0 interrupt 1 register (UF0INT1)
The UF0INT1 register is an 8-byte FIFO that stores data for Endpoint7 (to be passed to SIE).
This register is write-only, in 8-bit units. When this register is read, 00H is read.
The hardware transmits data to the USB bus in synchronization with the IN token for Endpoint7 only when the
IT1NK bit of the UF0EN register is set to 1 (when NAK is not transmitted). When the data is transmitted and
the host correctly receives it, the IT1NK bit of the UF0EN register is automatically cleared to 0 by hardware. A
short packet is transmitted when data is written to the UF0INT1 register and the IT1DEND bit of the
UF0DEND register is set to 1 (IT1 bit of the UF0EPS0 register = 1 (data exists)). A Null packet is transmitted
when the UF0INT1 register is cleared and the IT1DEND bit of the UF0DEND register is set to 1 (IT1 bit of the
UF0EPS0 register = 1 (data exists)).
