5.3.6 BOOT Configuration
All TPS65917-Q1 resource settings are stored in registers. Therefore, any platform-related settings are linked to an action which alters these registers. This action is either a static update (register initialization value) or a dynamic update of the register (from the user or 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, the SMPS and LDO default voltages, GPIO functionality, and TPS65917-Q1 switch-on events.
Sequence platform settingsThese settings define TPS65917-Q1 power sequences between state transitions An example includes the OFF2ACT sequence when transitioning from OFF state to ACTIVE state. Each power sequence is composed of several register accesses that define the resources (and the corresponding registers) that must be updated during the respective state transition. Small modifications from the main sequence can be defined with the BOOT pin as long as the OTP memory size constraint is respected. The user can overwrite these settings when the power sequence completes.
