3.2.8 Begin Externally Timed Programming

The data to be programmed must be previously loaded by the Load Data for NVM command before every Begin Externally Timed Programming command. To complete the programming, the End Externally Timed Programming command must be sent in the specified time window defined by T_PEXT (see Figure 3-13). The lower LSbs of the address are ignored.

Externally timed writes are not supported for the Configuration Words. Any externally timed write to the Configuration Words will have no effect on the targeted word.
