1.6.3.5
The RAM arrays are not initialized out of reset with exception of the EEE buffer RAM (providing the EEE
functionality is enabled).
1.6.3.6
The COP timeout rate bits CR[2:0] and the WCOP bit in the COPCTL register are loaded on rising edge
of RESET from the Flash register FOPT. See
is loaded from the Flash configuration field byte at global address $7FFF0E during the reset sequence.
If the MCU is secured and COP is enabled, the COP timeout rate is always set to the longest period
(CR[2:0] = 111) after COP reset and after any reset into Special Single Chip mode.
