Question
SPC58EN84C3 ADC test channel initialize error.
I tried to initialize test channels on SARADC_B (supervisor).
/* Channels Configurations (DMA is not used)*/
static channelConfig _saradcconf_ch_configs[SPC5_SARADC_MAX_NUMOFCHANNELS] =

};saradc_lld_start(&SARADC12DSV, &saradc_config_saradcconf);While debugging I realized it goes to '.unhandled_exception2' when I tried to set TCDR[x].B.PCE (precharge bit.)
I tried to set all precharge disabled and enabled, but it still not working.
Here are some screenshots from debug view.
