3.5.2.3 Bulk Erase
The following program segment demonstrates how to bulk erase the 512-byte EE-
PROM. The CONFIG register is not affected in this example.
3.5.2.4 Row Erase
The following program segment demonstrates the row erase function. A ‘row’ is six-
teen bytes ($B600-$B60F, $B610-$B61F... $B7F0-$B7FF). This type of erase opera-
tion saves time compared to byte erase when large sections of EEPROM are to be
erased.
* On entry, A = data to be programmed and X = EEPROM address
