It provides a variety of fast addressing modes for accessing the internal RAM to facilitate byte operations on small data structures. With the bit set, ALE is active only dur-.
The AT89C51 is normally shipped with the on- chip Flash Data Polling: The AT89C51 features Data Polling to indi- memory array in the erased state ( that is, contents = FFH) cate the end of a write cycle. The byte- write cycle is self- timed and typically takes no more than 1. Repeat steps 1 through 5, changing the address 6 AT89C51 and data for the entire array or until the end of the object file is reached. Data Polling: The AT89C51 features Data Polling to indicate the end of a write cycle.
