27.4.4 Debug Operation
When the CPU is halted in Debug mode, the ECC feature of the NVMCTRL will correct and log ECC errors based on the table below.
| DBGCTRL.ECCELOG | DBGCTRL.ECCDIS | DBGCTRL.ECCDIS |
|---|---|---|
| 0 | 0 | ECC errors from debugger reads are corrected, but not logged in INTFLAG. |
| 1 | 0 | ECC errors from debugger reads are corrected and logged in INTFLAG. |
| X | 1 | ECC errors from debugger reads are neither corrected nor logged in INTFLAG. |
Access to the NVM block can be protected by the security bit. In this case, the NVM block will not be accessible. See the section on the NVMCTRL 27.5.10 Security Bit for details.
