3:
x = unknown, u = unchanged, — = unimplemented, q = value depends on condition, r = reserved, do not modify.
CLKRDY resets to ‘0’ on Power-on Reset but is unaffected on all other Resets.
EREVID is a read-only register.
ECOCON resets to ‘---- -100’ on Power-on Reset and ‘---- -uuu’ on all other Resets.
