USB Interrupt Select Register 3 (UISR3)

UISR3 sets

EXIRQ to output interrupt request indicated in the interrupt flag register 3 (UIFR3).

When a bit in UIER3 corresponding to the UISR3 bit is cleared to 0, an interrupt request is output

from

EXIRQ0. When a bit in UIER3 corresponding to the UISR3 bit is set to 1, an interrupt

request is output from

EXIRQ1.

USB Data Status Register (UDSR)

UDSR indicates whether the IN FIFO data registers (EP1, and EP3) contain valid data or not. A bit

in USDR is set when data written to the corresponding IN FIFO becomes valid after the

corresponding PKTE bit in UTRG is set to 1. A bit in USDR is cleared when all valid data is sent

to the host. For EP1, having a dual-FIFO configuration, the corresponding bit in USDR is cleared

to 0 and FIFO becomes empty.
