0xC

Length

0x5

Addr_MSB

Most Significant Byte of 24-bit address

Addr_LSW

Least Significant 16 bits of 24-bit address

Size

Number of 24-bit locations (address range divided by two)

The CRCP command performs a CRC-16 on the range of memory specified. This command can substitute for a full chip verify. Data is shifted in a packed method as shown in Table 4-4, bytewise, Least Significant Byte (LSB) first.

Example:

CRC-CCITT-16 with test data of “123456789” becomes 0x29B1

Expected Response (3 words):

QE_Code: 0x1C00

Length: 0x0003

CRC Value: 0xXXXX
