5.14 Function Reset and Power-Up Reset Interconnect

Figure 5−1 represents the logical connection of the USB-function-reset (USBR) and power-up-reset (RSTI) pins. The

internal RESET signal is generated from the RSTI pin (PURS signal) or from the USB-reset (USBR signal). The USBR

can be enabled or disabled by the FRSTE bit in the USBCTL register (on power-up, FRSTE = 0). The internal RESET

is used to reset all registers and logic with the exception of the USBCTL and GLOBCTL registers, which are cleared

by the PURS signal only. As shown, the RESET/RESET is connected to the MUX, which controls the RSTO output

polarity (the MUX is controlled by the GLOBCTL register). In the development mode, the RSTO signal is used to reset

the external microcontroller or other devices.
