level

level 3, low byte (value = 44); element or word
mask byte: indicates 3 levels in the address. Level 1 uses
the default (0). Therefore, only levels 2 and 3 will be
encoded.
FF flag indicating the next level is too large (300) to encode
in one byte so it will be encoded into the next 2 bytes.
level 3, high byte (value = 256); element or word
