J5 Jumper to select both-chip-powered configuration in the two-chip EMCA solution:
Open: Default jumper position for the one-chip EMCA solution shown in Figure 3-5
or the two-chip solution with only one of the chips powered shown in Figure 3-7 .
Short: Jumper position for the two-chip EMCA solution with both chips powered
shown in
Figure 3-9 . It shorts the VDDD pins of U1 and U2.
Note: The configuration with both chips powered will work in this DVK irrespective of
which Type-C plug connector, J1 or J2, is connected to the DFP.

measurement
J6
To measure current, open the jumper and connect multimeter terminals between
pins 1 and 2. The measured current is the total current consumed by the CY4502
board, including the LEDs, when the J1 connector is connected to the host (that is,
when the DVK is powered using VCONN from Type-C plug, J1).
