DS1678 Real-Time Event Recorder
10 of 25
The user can write only to the RTC, control registers, and user NV RAM. The rest of the memory map is
read-only from the user’s perspective. During an event-log mission, all the memory is read-only. A write
terminates the mission. If there is an event being recorded when the mission is terminated, the event
finishes being recorded before the mission is stopped, and the values in the MIP and ME bits do not
change to zeros until the mission is complete.
During an event-log mission, memory locations 30h and above are not accessible to the user to avoid data
collisions from a user read and an event being logged at the same time. If the user tries to read a location
with an address greater than 2Fh during a mission, the value returned is 00h.
