8.4.3 Summary tables
In UART mode, the OTG Controller is allowed to connect a UART to the DAT/VP and
SE0/VM pins of the ISP1301.
UART mode is entered by setting the UART_EN bit in the Mode Control 1 register. UART
mode is equivalent to one of transparent general purpose buffer mode (bit
TRANSP_BDIR1 = 1, bit TRANSP_BDIR0 = 0).

BUS
In USB suspend mode, the ISP1301 can drive the DP and DM lines, if the OE_N/INT_N input (when the
OE_INT_EN bit is not set) is LOW. In such a case, these outputs are driven as in USB functional modes,
but with the full-speed characteristics, irrespective of the value of the SPEED input pin or the SPEED_REG
bit.
