USB Test Register 0 (UTSTR0)

UTSTR0 controls the on-chip transceiver output signals. Setting the PTSTE bit to 1 after setting

UIFRST and UDCRST in UCTLR to 0 specifies the transceiver output signals (USD+ and USD-)

arbitrarily. Table 14.2 shows the relationship between UTSTR0 setting and pin output.
