BOOT Configuration, Switch-ON, and Switch-OFF Sequences

The power sequence is the automated switch-on of the devices resources when an OFF-to-ACTIVE transition occurs. The power-on sequence has 15 sequential time slots to which resources (DC-DC converters, LDOs, 32-kHz clock, GPIO0, GPIO2, GPIO6, GPIO7) can be assigned. The time slot length can be selected to be 0.5 ms or 2 ms. If a resource is not assigned to any time slot, it will be in off mode after the power-on sequence and the voltage level can be changed through the register SEL bits before enabling the resource.

Power off disables all power resources at the same time by default. By setting the PWR_OFF_SEQ control bit to 1, power off will follow the power-up sequence in reverse order (the first resource to be powered on will be last to power off).

The values of VDD1, VDD2, and VDDCtrl set in the boot sequence can be selected from 16 steps. For the whole range, 100-mV steps are available: 0.6/0.7...1.4/1.5 V. From 0.8 to 1.4 V, additional values with
50-mV step resolution can be set: 0.85/1.05...1.35 V.

For LDO1, LDO2, and LDO4 all levels from 1.0 to 3.3 V are selectable in the boot sequence with 50-mV steps. For other LDOs, the level is selectable with 100-mV steps, from 1.0 to 3.3 V.

The device supports three boot configurations, which define the power sequence and several device control bits. The boot configuration is selectable by the device BOOT1 pin.

Floating Test boot mode
0 Fixed boot mode
1 EEPROM boot mode

The BOOT1 input pad is disabled after the boot mode is read at power up, to save power.

Table 6-2 and Table 6-3 describe the power sequence and general control bits defined in the boot sequence, respectively.

Fixed boot mode is the same in all devices, while EEPROM boot mode is different in each device. For a description of EEPROM boot mode, refer to the user's guide for the selected device. For a list of user's guides, see Section 8.2.1 or the device product folder on ti.com.
