4.3.11
The Bulk Erase Program Memory command performs
two different functions dependent on the current state
of the address.
A Bulk Erase Program Memory command should not
be issued when the address is greater than 8008h.
FIGURE 4-11:
4.3.12
To perform an erase of the data memory, after a Bulk
Erase Data Memory command, wait a minimum of
T
To erase data memory when data code-protect is active
(CPD = 0), the Bulk Erase Program Memory command
should be used.
