The IRIS-W10 module SWD interface, GPIO13-SWDCLK and GPIO14-SWDIO , are connected
to the MCU-LINK interface and J45 needles connector simultaneously by default through 0R
resistors R2 and R12 those GPIOs could be also connected to J20 by disconnecting the last
two resistors and populate resistors R48, R116 with 0 R. See connections in Figure 24 .
GPIOs 13 and 14 are also accessible through pin headers J47 ( pin 2) and J48 ( pin 1) ,
respectively. By toggling the USB switch
U19
by disconnecting
R257, R142, R143
and
populating R258 with 0R (or in case of U19 is not populated), previous pins can be accessed
from the pin headers by populating
R142, R143
with
0R.
Note that
U19
and
R142, R143
should not be populated simultaneously .
The JTAG interface of the IRIS-W10 module is connected to J20 and FTDI chip through
resistors, and pin headers simultaneously by default, as shown in Table 10 .
Jumpers grouped in Table 10 and Figure 26 should be set to their default connections, as
shown in Figure 25 .
