CC: Invasive and Non-Invasive debug enable settings are reset by MCU_RESETz
The CTRLMMR_MCUSEC_CLSTR0_CORE[1:0]_DBG_CFG registers are erroneously reset to default values after asserting MCU_RESETz. They should only be reset on assertion of PORz. Therefore, any changes made to this register by software to affect Invasive and Non-invasive debug operation will be overwritten upon assertion of MCU_RESETz.
Software should reprogram the CTRLMMR_MCUSEC_CLSTR0_CORE[1:0]_DBG_CFG registers after MCU_RESETz is asserted.
