32.5 Memory map and registers description
Table 429 shows the CRC memory map.
CRC configuration
(polynomial, swap, inversion)
setting the CRC_CFG register
CRC seed initialization
(CRC_CSTAT register)
Data is written in the CRC_INP
register (byte/half word/word)
by CPU or DMA
CRC signature available
in the CRC_OUTP register)
START
context = 1
context = n
All the data
has been passed to the
