If multiple errors from above occur at the same time, the detail code will be the sum and indicated in
hexadecimal notation; for example,
If BD error (0001), B shading correction RAM error (0004), and G shading correction RAM error
(0008) occur at the same time, the indication will be
0001 + 0004 + 0010 = 001C.
