Further, transmitting garbage data just bricks the transfer\nsince QSPI doesn't have a dedicated master-out line like MOSI in regular\nSPI. I'm not entirely sure if the transfer is bricked because of the\ngarbage data being transmitted on the bus or because the core loses\ntrack of whether it is supposed to be sending or receiving data."
