Parameters (in)

Parameter mode selects the behavior of the L9952GXP after Vs (power supply

voltage) recovery

Return value

None

Description

This function enables automatic recovery of outputs after Vs over/under voltage

recovery of the L9952GXP.

The register affected is the CR2.4(1)(2)

1. This function updates the software driver’s internal copy of control register 2 and sends it immediately to

the L9952GXP via the SPI.

2. This function refreshes the software driver’s internal copy of status 0 register from the L9952GXP via the

SPI.

Caveats

This function waits until the data are completely transferred to the L9952GXP

via the SPI.

Configuration

None
