nRF51822 SPI with more than one CS signal

Question

how can I program SPI to select more than only one slave device with any GPIO ? 
 SPI Routine "spi_master_int" can select SPI0 or SPI1 only with one dedicated GPIO as Slave-Select Signal.

Hi Reinhard, 
 The SPI master module only sets CLK/MISO/MOSI. It does not hard-code the chip select.
The chip-select is a GPIO (or several) that must be handled in your application to differentiate between several SPI-slaves. 
 Very basic pseudo code: 
 CS_SLAVE_0 = active;
SPI_COMMUNICATION();
CS_SLAVE_0 = inactive; 
 CS_SLAVE_1 = active:
SPI_COMMUNICATION();
CS_SLAVE_1 = inactive; 
 Best regards
Håkon
