PCS[0:5] signals of SPI module

Hello All,

Can we assert all PCS[0:5] signals of SPI module, simultaneously? I just want to check the possibility of using other PCS signals instead of GPIOs as Slave RESET pins when my Master is configuring address of First slave after power up. We will have only one PCS signal connected to All the slaves. In user manual of LS1021A, it is mentioned that "6 peripheral chip selects (PCSes), expandable to 64 with external demultiplexer". We do not require external demultiplexer for our application.


Thank you.
