10.8. Software Reset
Software may force a reset by writing a ‘1’ to the SWRSF bit (RSTSRC.4). The SWRSF bit will read ‘1’ fol-
lowing a software forced reset. The state of the /RST pin is unaffected by this reset.
10.9. USB Reset
Writing ‘1’ to the USBRSF bit in register RSTSRC selects USB0 as a reset source. With USB0 selected as
a reset source, a system reset will be generated when either of the following occur:
The USBRSF bit will read ‘1’ following a USB reset. The state of the /RST pin is unaffected by this reset.
1. RESET signaling is detected on the USB network. The USB Function Controller (USB0) must
2. The voltage on the VBUS pin matches the polarity selected by the VBPOL bit in register
be enabled for RESET signaling to be detected. See Section “15. Universal Serial Bus Con-
troller (USB)” on page 139 for information on the USB Function Controller.
REG0CN. See Section “8. Voltage Regulator (REG0)” on page 67 for details on the VBUS
detection circuit.
