Detailed Description

Full configuration descriptor for ra8_ceu_init.

Every CEU register that has to be programmed at open time is driven from this single struct. Optional features are switched on/off by a flag instead of needing a separate setter call:

  • Set interlace to enable interlace capture (CAIFR.IFS=1).
  • Set bundle_write to enable bundle-write mode (CDOCR.CBE=1).
  • Set low_pass_filter to enable the input LPF (CLFCR.LPF=1).
  • Set scale.h_* or scale.v_* non-zero to enable scale-down.

cppcheck cannot see tests/ so it flags every field as unused; each member is read in ra8_ceu_init in libs/ra8_hal/src/ra8_ceu.c.
