8.4.1 Boot

At initial power on the device goes through a boot routine. This routine is responsible for initializing device register values and loading device patch and configuration bundles. The device's functional behavior after boot can be configured through the use of pin straps on the SPI_POCI and ADCIN1 pins as shown inTable 8-7.

(1) External resistor tolerance of 1% is required. Resistor values must be chosen to yield a DIV value centered nominally between listed MIN and MAX values.

The pin strapping configures two different parameters, Dead battery mode and device configuration. The dead battery mode selects device behavior when powered from VBUS. The dead battery mode behaviors are detailed in Table 8-8.

Table 8-8 Dead Battery Configurations
CONFIGURATIONDESCRIPTION
BP_NoResponseNo power switch is enabled and the device does not start-up until VIN_3V3 is present
BP_WaitFor3V3_InternalThe internal power switch from VBUSx to PP_HVx is enabled for the port receiving power. The device does not continue to start-up or attempt to load device configurations until VIN_3V3 is present.
BP_WaitFor3V3_ExternalThe external power switch from VBUSx to PP_HVx is enabled for the port receiving power. The device does not continue to start-up or attempt to load device configurations until VIN_3V3 is present.
BP_ECWait_InternalThe internal power switch from VBUSx to PP_HVx is enabled for the port receiving power. The device infinitely tries to load configuration.
BP_ECWait_ExternalThe external power switch from VBUSx to PP_HVx is enabled for the port receiving power. The device infinitely tries to load configuration.
BP_NoWaitThe device continues to start-up and attempts to load configurations while receiving power from VBUS. Once configuration is loaded the appropriate power switch is closed based on the loaded configuration.
Note:

Devices implementing the BP_WaitFor3V3_External configuration must use GPIO16 for port 1 external path control and GPIO17 for port 2 external path control.

When powering up from VIN_3V3 or VBUS the device will attempt to load configuration information from the SPI or I2C digital interfaces. The device configuration settings select the device behavior should configuration information not be available during the device boot process. Table 8-9 shows the device behavior for each device configuration setting.
