S105FFFEFC0001

S9030000FC

a) Verify the length and checksum for the first record only

b) Disassemble the code to produce the corresponding list file in simple assembler format.

Solution

a)

First record length is 32 since hex value given record has 32 bits long and checksum is 45

b)

Disasembling the code to produce the equivalent assembler format.
