Terminating a signal to the wrong IO supply rail can cause leakage between the IO rails of the processor. Each signal has an associated IO supply rail (Ex: VDDSHVx [x=0-5]). For more information, see the Pin Attributes table of the device-specific data sheet.
For example, if you want to pullup SPI0_CS1 signal in any mux mode (UART6_RXD, I2C2_SCL, GPIO1_43 and so forth), pull up the signal supply rail connected to VDDSHV0.
