◆ crc_calculate()
| uint32_t crc_calculate | ( | uint32_t | data | ) |
Writes a data word to the register, the write operation stalling until the computation is complete.
- Parameters
-
[in] data new word to add to the CRC calculator
- Returns
- int32 Computed CRC result
Definition at line 36 of file crc_common_all.c.
References CRC_DR.
◆ crc_calculate_block()
| uint32_t crc_calculate_block | ( | uint32_t * | datap, |
| int | size | ||
| ) |
Add a block of data to the CRC calculator and return the final result.
Writes data words consecutively to the register, the write operation stalling until the computation of each word is complete, then returns the final result
- Parameters
-
[in] datap pointer to an array of 32 bit data words. [in] size length of data, in 32bit increments
- Returns
- final CRC calculator value

◆ crc_reset()
| void crc_reset | ( | void | ) |
Reset the CRC calculator to initial values.
Definition at line 31 of file crc_common_all.c.
