Infineon SAK-TC375TP-96F300W AA - Optional resistors

AURIX™ lite Kit V2
Hardware Description
Board Users Manual 15 Revision October, 2020
3.3 Optional resistors
Some resistors/bridges enable/disable or changing functions of specific signals in Table 8.
To disable the signals, the resistors have to be removed. To enable, the resistor has to be assembled.
For example: Desoldering the intialy assembled resistor R33, disables the Potentiometer and the analog Signal
AN0 of the AURIX™, making it usable for other purposes.
