how to select and unselect DSPI slave select lines

[Yali Mobilities]

while using the DSPI example in spc58ec_disp , i couldn't see that the "spi_lld_select" and "spi_lld_unselect " functions usage to control the slave pin. and it didn't had any effect while i used the functions. how could i use the functions to control the chip select line.

Hi,

if the DSPI is configured in Slave mode, its Chip Select (and Clock) must be driven by a DSPI master.
