(Addresses of first word in page). The erase must be enabled using CONFIG.WEN before the page can be erased. Attempts to erase pages that are outside the code area may result in undesirable behavior, e.g. the wrong page may be erased. 4.3.9.5 ERASEPCR1 ( Deprecated ) Address offset: 0x508 Register for erasing a page in code area, equivalent to ERASEPAGE Bit number 31 30 29 28 27 26 25 24 23 22 21 20 19 18 17 16 15 14 13 12 11 10 9 8 7 6 5 4 3 2 1 0 ID A A A A A A A A A A A A A A A A A A A A A A A A A A A A A A A A Reset 0x00000000 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 ID Access Field Value ID Value Description A W ERASEPCR1 Register for erasing a page in code area, equivalent to ERASEPAGE 4.3.9.6 ERASEALL Address offset: 0x50C Register for erasing all non-volatile user memory 4463_156 v1.0 22 |
