Connecting a signal pullup to the wrong IO supply rail could cause leakage between the IO rails of the processor and affect the custom board performance/processor reliability. Each signal has an associated IO supply rail (Ex: VDDSHVx [x=0..6]). For more information, refer the Pin Attributes table in the device-specific data sheet.
Example, if you want to pullup SPI0_CLK signal in any mux mode (EHRPWM1_A, GPIO1_17, and so forth), pullup the signal supply rail connected to VDDSHV0.
