ISPDAT
ISP Data
Write data to this register before ISP program operation.
Read data from this register after ISP read operation.
When ISPFF (FMC_ISPCTL[6]) is 1, ISPDAT = 0xffff_ffff. For Run CRC32 Checksum
Calculation command, ISPDAT is the memory size (byte) and 4 Kbytes alignment. For ISP
Read CRC32 Checksum command, ISPDAT is the checksum result. If ISPDAT =
0x0000_0000, it means that (1) the checksum calculation is in progress, or (2) the memory
range for checksum calculation is incorrect.
