24.3.1.1 Flash memory CRC control register (CRC0CTL)
This register is used to control the operation of the high-speed CRC ALU, as well as to specify the operation range.
The CRC0CTL register can be set by a 1-bit or 8-bit memory manipulation instruction.
Reset signal generation clears this register to 00H.
Figure 24 - 1 Format of Flash memory CRC control register (CRC0CTL)
Remark Input the expected CRC operation result value to be used for comparison in the lowest 4 bytes of the flash
memory. Note that the operation range will thereby be reduced by 4 bytes.
