This memory is initialized during the bitstream download process with reference data computed by NXmap software.
By default, the CMIC is disabledisabled.
CMIC Operation
CMIC Definition
...
To check if an uncorrectable error has been found the user has to read the ERROR1 and ERROR2 registers. Please refer to NanoXplore_NX1H35AS_Configuration _ Guide documentation.
In case of an uncorrectable error, the bitstream must be reloaded by asserting RST_N to low level during at least 50 CLK cycles – or 3 us (to reset the internal configuration engine), before going high to restart the configuration process.
...
The CMIC can be directly activated in NXmap, this option is documented in NXmap_user_manual /wiki/spaces/~814749387/pages/48660481.
The CMIC can be activated/deactivated by programming the LOADER_CTRL register.
This register is documented in the NG-MEDIUM configuration user’s guide Configuration Guide.
CMIC Period
The CMIC period can be set by defining parameters used during the bitstream generation.
