The scanner allows segments of the Program Flash Memory or Data EEPROM to be
read out (scanned) to the CRC peripheral. The scanner module interacts with the CRC
module and supplies it data, one word at a time. Data is fetched from the address range
defined by
SCANLADR registers up to the
SCANHADR registers. The scanner begins operation when the
SGO bit is set and ends when either SGO is cleared by the user or when
SCANLADR increments past SCANHADR. The SGO bit is also cleared when the
EN bit in the
CRCCON0 register is cleared.
