(15) UF0 INT status 4 register (UF0IS4)
UF0IS4
Bit position
This register indicates the interrupt source. If the contents of this register are changed, the INTUSB2B signal
becomes active.
This register is read-only, in 8-bit units.
If an interrupt request (INTUSB2B) 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 UF0IC4 register.
The related bits are invalid if each endpoint is not supported by the setting of the UF0EnIM register (n = 1, 2)
and the current setting of the interface.

register (n = 0 to 4).
5
1: The request has been automatically processed (interrupt request is generated).
0: The request has not been automatically processed (default value).
