USBCTL: USB Control Register
Unlike the rest of the registers, this register is cleared by the power-up-reset signal only. The USB-reset cannot reset
this register (see Figure 5–1).

BIT
NAME
RESET
FUNCTION
0
DIR
0
As a response to a setup packet, the MCU decodes the request and sets/clears this bit to reflect the data transfer
direction.
DIR = 0 USB data-OUT transaction (from host to TUSB5152).
DIR = 1 USB data-IN transaction (from TUSB5152 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 notserved. The MCU clears this bit before exiting the SETUP interrupt routine.
SIR = 1
SETUP interrupt is in progress. The MCU sets this bit when servicing the SETUP interrupt.
2
BS
0
BS = 0 Bus-powered hub
BS = 1 Self-powered hub
3
RSV
0
Reserved
4
FRSTE
1
Function reset-connection bit. This bit connects/disconnects the USB function reset to/from the MCU reset.
FRSTE =0 Function reset is not connected to MCU reset
FRSTE =1 Function reset is connected to MCU reset
5
RWUP
0
Device remote wake-up request. This bit is set by the MCU and is cleared automatically.
RWUP = 0
Writing a 0 to this bit has no effect.
RWUP = 1
When MCU writes a 1, a Remote wake-up pulse is generated.
6
U1/2
0
USB hub version
U1/2 = 0 This is a USB1.x hub.
U1/2 = 1 This is a USB2.x hub.
7
CONT
0
Connect/disconnect bit
CONT = 0 Upstream port is disconnected. Pullup disabled.
CONT = 1 Upstream port is connected. Pullup enabled.
