I'm trying to develop a diagnostic function for PT2001, but I don't know how to use it. For example, when I open the low or high side of the inj, the status register doesn't change. Please tell me how to use the diagnostic function and the detailed steps

Hi,

Please refer to our AN12336 - PT2001 diagnostics:

Can the hexadecimal data of microcode provided by AN4849 and the hexadecimal data of microcode of AN12336 be put in the same array, and then pass PT2001 through SPI, so that it has two functions of injection and diagnosis at the same time?
