TPS6593EVM: Enable Interrupt

Part Number: TPS6593EVM


if the signal "ENABLE_MASK" in the interrupt mask register is set to "Interrupt not generated.", the power up sequence does not start and all Buck and LDO outputs remain switched off. If the signal "ENABLE_MASK" is set to "Interrupt generated", the power up sequence runs as defined. Why must the interrupt be switched on? How can the issue solved otherwise, so that no "ENABLE_INT" is generated at power up or after switching the "PWRON/ENABLE" input from low to high?

"N_POWRN_SEL" is defined as "ENABLE" and "ENABLE_POL" as "Active high".
