Hello,
I want to change the register values (WDCFG0) of the TLF35584VS1. They are protected against being overwritten accidently. Therefore I sent a dedicated 32 Bit UNLOCK sequence via SPI: 0x8756, 0x87DE, 0x86AD and 0x8625.
I checked the status of the protection by reading the register PROTSTAT, I send 0x5000 on MOSI and received 0x8001 on MISO. That means the access to write protected registers is still locked.
So how can I get access to protected registers?
