uint8 mask

L9952drv_OutModeType mode

)

Service ID

Sync/async

Asynchronous

Reentrancy

Non reentrant

Parameters (in)

Parameter mask defines the outputs which should be configured

Address range: 0x00 .. 0xF1

Bit 0: 1 = Mask is active for OUTHS, 0 = Mask is not active for OUTHS

Bit 4: 1 = Mask is active for OUT1, 0 = Mask is not active for OUT1

Bit 5: 1 = Mask is active for OUT2, 0 = Mask is not active for OUT2

Bit 6: 1 = Mask is active for OUT3, 0 = Mask is not active for OUT3

Bit 7: 1 = Mask is active for OUT4, 0 = Mask is not active for OUT4

The following constants are defined in L9952drv.h file:

#define L9952DRV_MASK_OUTHS 0x01

#define L9952DRV_MASK_OUT1 0x10

#define L9952DRV_MASK_OUT2 0x20

#define L9952DRV_MASK_OUT3 0x40

#define L9952DRV_MASK_OUT4 0x80

Example: OUT_MODE_MASK_OUT1 | OUT_MODE_MASK_OUT2 ... mask

is active for OUT1 and OUT2.

Parameter mode sets the mode for selected outputs

Return value

None

Description

This function controls high side (HS) outputs of the L9952GXP

The registers affected are the CR0.0..14(1)(2)

1. This function updates the software driver’s internal copy of control register 0 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
