Table 23.

L9952drv_GetStatus1

Service name

L9952drv_GetStatus1

Syntax

Void L9952drv_GetStatus1

(

L9952drv_StatusRegType *DataPtr

)

Service ID

Sync/async

Asynchronous

Reentrancy

Non reentrant

Parameters (in)

Parameter *DataPtr points to variables which are filled with data from the status

1 register.

Return value

None

Description

This function reads the current status from the L9952GXP via the SPI and then

files the data structure in the staus 1 register(1)

1. Control register 1 is refreshed to the L9952GXP via the SPI using the software driver’s interanl copy of it.

Caveats

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

via the SPI.

Configuration

None

Table 24.

L9952drv_ReadStatus1

Service name

L9952drv_ReadStatus1

Syntax

Void L9952drv_ReadStatus1

(

L9952drv_StatusRegType *DataPtr

)

Service ID

Sync/async

Asynchronous

Reentrancy

Non reentrant

Parameters (in)

Parameter *DataPtr points to variables which are filled with data from the status

1 register.

Return value

None

Description

This function files data structure with the most recent software driver internal

copy of status 1 data.

Caveats

This function returns the internal copy of the data. The status 1 register is not

refreshed by reading its status from the L9952GXP via the SPI(1).

1. Use the L9952drv_GetStatus1() function to get actual refreshed data via the SPI.

Configuration

None
