All TPS65917-Q1 resource settings are stored in the form of registers. Therefore, all platform-related settings are linked to an action altering these registers. This action can be a static update (register initialization value) or a dynamic update of the register (either from the user or from a power sequence).
Resources and platform settings are stored in nonvolatile memory (OTP). These settings are defined as follows:
Static platform settingsThese settings define, for example, SMPS or LDO default voltages, and GPIO functionality. Most static platform settings can be overwritten by a power sequence or by the user.
Sequence platform settingsThese settings define the TPS65917-Q1 power sequences between state transitions, such as the OFF2ACT sequence when transitioning from OFF mode to ACTIVE mode. The power sequence is composed of several register accesses that define which resources (and the corresponding registers) must be updated during the respective state transition. The state of these resources can be overwritten by the user after the power sequence completes execution.
