(14) UF0 INT status 3 register (UF0IS3)
Remark
UF0IS3
Bit position
This register indicates the interrupt source. If the contents of this register are changed, the EPCINT1B signal
becomes active.
This register is read-only, in 8-bit units.
If an interrupt request (INTUSBF0) is generated from USBF, the FW must read this register to identify the interrupt
source.
Each bit of this register is forcibly cleared to 0 when 0 is written to the corresponding bit of the UF0IC3 register.
The related bits are invalid if each endpoint is not supported by the setting of the UF0EnIM register (n = 2, 4) and
the current setting of the interface.

NAK
These bits indicate that data has been correctly received in the UF0BOn register
(Endpoint m) and that both the FIFOs of the CPU and SIE hold the data.
If data is held in both the FIFOs of the CPU and SIE, these bits are automatically set to 1
by hardware. They are automatically cleared to 0 by hardware when the FIFO is toggled.
These bits indicate that a Null packet (packet with a length of 0) has been received in the
UF0BOn register (Endpoint m).
These bits are set to 1 immediately after reception of a Null packet when the FIFO is
empty. They are set to 1 when the FIFO on the CPU side has been completely read if
data is in that FIFO.
These bits indicate that an OUT token has been received to the UF0BOn register
(Endpoint m) and that NAK has been returned.
