I'm debugging on the basis of the TC1797 controller. As a result of the debugger crash, the controller was in the RESET state.
"RESET_TC.001 SCU_RSTSTAT.PORST not set by a combined
Debug / System / Application Reset
Causing simultaneously a System, Application, and Debug Reset via CBS_OSTATE.RSTCL0…3 in most cases does not leave the SCU_RSTSTAT.PORST bit set as specified. Bit SCU_RSTSTAT.PORST stays set only if reset source ESR0 was configured not to generate any reset (SCU_RSTCON.ESR0 = 00B). If the ESR0 reset source is configured to generate a reset, bit SCU_RSTSTAT.PORST is cleared and bit SCU_RSTSTAT.ESR0 is set instead.
Bits CBS_OSTATE.RSTCL0…3 are either set by setting bits CBS_OCNTRL.OJC4…7 or CBS_OJCONF.OJC4…7.
Debugging of “PORST-only” application software under debugger control is therefore not working if the ESR0 reset source generates a reset.
workaround
Before triggering a simultaneous System, Application, and Debug Reset by the OCDS system bit field SCU_RSTSTAT.ESR0 should be cleared. In addition, it should be checked that bit field SCU_RSTSTAT.ESR1 is also cleared. If bit field SCU_RSTSTAT.ESR0 needs to contain a value different from 00Binstead of checking bit SCU_RSTSTAT.PORST the three bits SCU_RSTSTATCB0, SCU_RSTSTATCB1, and SCU_RSTSTATCB3 should be checked to be set."

But nothing happens during the connection, the ESR0 Configuration Register and ESR1 Configuration Register are not reset. Please tell me how to reset these registers using commands in MEMTOOL?
