/*******************************************************************************
* Function Name: SPI_SpiStop
********************************************************************************
*
* Summary:
* Changes the HSIOM settings for the SPI master output pins (SCLK and/or SS0-SS3) to
* keep them inactive after the block is disabled. The output pins are
* controlled by the GPIO data register.
*
* Parameters:
* None
*
* Return:
* None
*
