(

uint8 mask

L9952drv_OutOLThresholdLevelType level

)

Service ID

Reentrancy

Non reentrant

Parameters (in)

Parameter mask sets the openload detection level (OLT) for related HS outputs

Address range: 0x00 .. 0xF0

Bit 4: 1 = Mask active for OUT 1, 0 = Mask not active for OUT 1

Bit 5: 1 = Mask active for OUT 2, 0 = Mask not active for OUT 2

Bit 6: 1 = Mask active for OUT 3, 0 = Mask not active for OUT 3

Bit 7: 1 = Mask active for OUT 4, 0 = Mask not active for OUT 4

Following constants are defined in L9952drv.h file

#define L9952DRV_MASK_OUT1 0x10

#define L9952DRV_MASK_OUT2 0x20

#define L9952DRV_MASK_OUT3 0x40

#define L9952DRV_MASK_OUT4 0x80

Example: L9952DRV_MASK_OUT1 | L9952DRV_MASK_OUT 4 ... mask is

active for OUT1 and OUT4.

Parameter level defines level for open load detection for related HS outputs

Return value

None

Description

This function sets the openload detection level for selected HS outputs 1..4 of

the L9952GXP.

The registers affected are the CR2.0..3(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
