Valid entries are: B (byte), K (Kilo), M (Mega) ● 1 digit for the sector type as follows: – a (0x41): Readable – b (0x42): Erasable – c (0x43): Readable and Erasabled (0x44): Writeable – e (0x45): Readable and Writeable – f (0x46): Erasable and Writeable – g (0x47): Readable, Erasable and Writeable Note: If the target memory is not contiguous, the user can add the new sectors to be decoded just after a slash"/" as shown in the following example: "@Flash /0xF000/1*4Ka/0xE000/1*4Kg/0x8000/2*24Kg"
