Erasing code or data EEPROM is accomplished by
writing an “erase option” to address 3C0004h. Code
memory may be erased portions at a time, or the user
may erase the entire device in one action. “Bulk Erase”
operations will also clear any code protect settings
associated with the memory block erased. Erase
options are detailed in Table 3-1.
TABLE 3-1:
The actual Bulk Erase function is a self-timed opera-
tion. Once the erase has started (falling edge of the 4th
PGC after the NOP command), serial execution will
cease until the erase completes (parameter P11). Dur-
ing this time, PGC may continue to toggle but PGD
must be held low.
The code sequence to erase the entire device is shown
in Figure 3-2 and the flow chart is shown in Figure 3-1.
