Detailed Description

CRC peripheral register block.

Re-derived against FSP R_CRC_Type in R7KA8D2KF_core0.h. Total size is exactly 16 bytes. CRCDIR/CRCDIR_BY and CRCDOR/CRCDOR_HA/ CRCDOR_BY share their physical address; the BY/HA alias members are placed in unions so byte/half-word/word writes hit the same register and the hardware uses CRCCR0.GPS to interpret width.
