8.3 USB modes
8.4 Transparent modes
In direct I
communicates with the serial controller through the SCL and SDA lines. The serial
controller has a built-in I
In this mode, an external I

The supported I
The ISP1301 is in direct I
OE_N/INT_N is de-asserted.
The four USB modes of the ISP1301 are:
In VP_VM USB mode, the DAT/VP pin is used for the VP function, the SE0/VM pin is used
for the VM function, and the RCV pin is used for the RCV function.
In DAT_SE0 USB mode, the DAT/VP pin is used for the DAT function, the SE0/VM pin is
used for the SE0 function, and the RCV pin is not used.
In unidirectional mode, the DAT/VP and SE0/VM pins are always inputs. In bidirectional
mode, the direction of these signals depends on the OE_N/INT_N input.
Table 6
The ISP1301 is in USB mode when both the TRANSP_EN and UART_EN bits are
cleared.
In transparent general-purpose buffer mode, the DAT/VP and SE0/VM pins are connected
to the DP and DM pins, respectively. Using bits TRANSP_BDIR1 and TRANSP_BDIR0 of
the Mode Control 2 register as specified in
transfer. The ISP1301 is in transparent general-purpose buffer mode if bit
TRANSP_EN = 1 and bit DAT_SE0 = 1.
When in transparent UART mode, the ATX behaves as two logic level translator between
the following pins:
