Legend:

= unknown, u = unchanged, — = unimplemented, q = value depends on condition, r = reserved, do not modify.

Note

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.
