Summary of VCCIO-configuration
On the TE0705 TEBA0841 carrier board all the PL IO-bank's supply voltages of the 4x5 SoM (VCCIOA, VCCIOB, VCCIOC, VCCIOD; see 4x5 Module Integration Guide) are connected to the base-board VCCIO-voltage VIOTB, which is either fixed to 3.3V (J21: 1-2, 3) or selectable with the adjustable supply-voltage VADJ (J21: 1, 2-3). The supply-voltages have following pin-assignments on B2B-connectors:
VCCIOA and VCCIOA, which are selectable between the supply-voltages 1.8V, 2.5V and 3.3V via jumper J26 and J27

Note: The corresponding PL IO-voltage supply voltages of the 4x5 SoM to the selectable base-board voltage VIOTB are depending on the mounted 4x5 SoM and varying in order of the used model. Refer to SoM's schematic to get information about the specific pin-assignment on module's B2B-connectors regarding PL IO-bank supply voltages and to the 4x5 Module integration Guide for VCCIO voltage options. |
Following table describes how to configure the base-board supply-voltages by jumpers:

| 3.3V | J26:5-6 | J27:5-6 |
Table 5: Configuration of base-board supply-voltages via jumpers. Jumper-Notification: 'Jx: 1-2, 3' means pins 1 and 2 are connected, 3 is open. 'Jx: 1, 23-34' means pins 2 3 and 3 4 are connected, 1 is openand so on.
| Note |
|---|
| It is recommended to set and measure the PL IO-bank supply-voltages before mounting of TE 4x5 module to avoid failures and damages to the functionality of the mounted SoM. |
