Unlike the other registers, this register is cleared by the power-up-reset signal only. The USB reset cannot
reset this register (see the reset diagram in Figure 2-2 ).

0 DIR 0 As a response to a setup packet, the MCU decodes the request and sets or clears this bit to reflect the
data transfer direction.
DIR = 0 USB data OUT transaction (from host to TUSB3210)
DIR = 1 USB data IN transaction (from TUSB3210 to host)
1 SIR 0 SETUP interrupt status bit. This bit is controlled by the MCU to indicate to the hardware when the SETUP
interrupt is being served.
SIR = 0 SETUP interrupt is not served. MCU clears this bit before exiting the SETUP interrupt
routine.
SIR = 1 SETUP interrupt is in progress. MCU sets this bit when servicing the SETUP interrupt.
2 B/S 0 Bus-/self-power control bit
B/S = 0 The device is bus-powered.
B/S = 1 The device is self-powered.
