XS1-L1 128TQFP Datasheet (2.2)
The XS1-L1 device contains a standard 5 pin JTAG interface, which allows the following
The JTAG interface on the XS1-L1 consists of the following signals:
The TRST_N pin must be driven low for at least 100ns after the power supplies are

3.6 JTAG Operation
functionality:
stable to reset the JTAG circuitry. If JTAG debug is not required, the TRST_N pin can
be tied to ground to hold the JTAG port in reset.
Each XS1-L device contains multiple TAP controllers, each enabling different func-
tionality. Directly after reset, two TAP controllers are present in the JTAG chain - the
boundary scan TAP (BS TAP) and the chip TAP (CHIP TAP).
