7.4 Device Functional Modes

The device can operate in two modes: pin mode or SPI mode. When the SPI/PIN pin is low, the device operates in pin mode. When the SPI/PIN pin is high, the device operates in SPI mode.

The CQ driver control in either of the modes is described in Table 7-6. The DO driver control is described in Table 7-7. Additionally, if using SPI mode, both CQ and DO driver can be connected together to drive higher load currents. The settings for this configuration is described in Table 7-8 and CQ and DO Tracking mode. The recommended is to have the drivers in disabled state before changing the driver configuration settings including the driver modes, current limits and overcurrent blanking time.

Table 7-8 DO Control (When DO_CQ_TRACK = 1b) When DO and CQ are set to track (DO_CQ_TRACK set to 1b), DO driver follows the CQ configuration and the DO configuration is ignored, including the driver modes, current limits and driver settings.
