42 write protect" GPIO that is connected to the AP SPI flash, EC SPI flash,
44 protect" can only be disabled with servo or suzyq (["CCD open"]) and
45 corresponds to [`OverrideWP`] in ccd. Disabling this write protect disables it
48 In the case of the FPMCU, the hardware write protect GPIO is tied to the STM32
51 You may see various references to a [write protect screw in
52 documentation][wp_screw]. Older Chrome OS devices had a write protect screw

102 Software-based write protect state stored in non-volatile memory. If hardware
103 write protect is enabled, software write protect can be enabled but can’t be
104 disabled. If hardware write protect is disabled, software write protect can be

108 The underlying mechanism implementing software write protect may differ between
109 EC chips. However the common requirements are that software write protect can
110 only be disabled when hardware write protect is off and that the RO firmware
