I have a PCB with 142 pin connected to a pull-up resistor. I use correctly a spi flash. After a minute, I enter in LPWFI mode and disable BPSI1 by a BSPI_Enable (BSPI1,DISABLE); command After an interrupt, the program restart and enable the bspi but the BPSI1 component detect a bus error. I don't understand why. Thank's,
