Setting a MISO pin to 0 as an IO

I am using a BLE (Bluetooth Low Energy) controller that is connected via SPI to a Kinetis controller. At one moment, in order to trigger a transmission from the BTLE controller, I have to set the MOSI pin to a 0 level, but as much as I tried, Icouldn't. I have defined the MOSI pin as a shared pin in PE but I wasn't able to pull it to GND. Can you please help me?
