TDA2x - Is it possible to set QSPI pins to high impedance?

We have one flash connected to two SPI controllers:

- One to an SPI controller from an MCU;

- One to a QSPI controller from a TDA2x.

Under certain situations, we need to disable the connection between the flash and TI QSPI controller, to allow the MCU to manipulate the flash exclusively.

So is it possible to set TI QSPI pins to high impedance, or simply clearing the SPI ENABLE bit in SPCR is enough?
