4.2.9
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 2008h.
FIGURE 4-9:
4.2.10
This command erases the 32-word row of program
memory pointed to by PC<13:5>. If the program
memory array is protected (CP = 0) or the PC points to
the configuration memory (> 0x2000), the command is
ignored. When the address is 2000h-2008h, the Row
Erase Program Memory command will only erase the
user ID locations, regardless of the configuration bit CP
setting.
After receiving the Row Erase Program Memory
command, the erase will not be complete until the time
interval, T
