CHAPTER 2 "PCL" - 82
If the control bit is 0, replacement data is not repeated data. Bits 6 to 3 contain the offset count. This field
value is from 0 to 15. If this value is 15, the next byte of the control bytes is an optional offset count. The
value of this optional offset count byte is from 0 to 255. If this optional offset count value is 255, then the
next byte is another (second) optional offset count byte. Optional offset count bytes will continue until the
value is less than 255. The total Offset value is the sum of the offset count in the control byte and all the
optional offset bytes.
Bits 2 to 0 of the control byte contains the replacement count - 1. The value is from 0 to 7. If this value is 7,
optional replacement byte(s) follow the control byte or optional offset byte(s) (if any).
If the first optional replacement count byte is 255, then a second optional count byte follows the first optional
count byte. Optional offset count bytes will continue until the value becomes less than 255. The addition of
the replacement count in the control byte and all optional replacement count bytes gives the total replacement
count.
Replacement data bytes follow the control byte and any optional offset bytes and any optional replacement
count bytes.

Command byte for mode 9 compression (repeated replacement data)
If the control bit is 1, replacement data is repeated data. Bits 6 to 5 contain the offset count and bits 4 to 0
contain the 'replacement count (repeat count) - 2'.
If bit 6 and bit 5 are '1', then an optional offset byte follows the control byte. If the value of this optional offset
byte is 255, another (second) optional offset byte follows the first optional offset byte. The addition of the
offset count in the control byte and any optional offset bytes gives the total offset count.
If bits 4 to 0 are all '1', an optional replacement count byte follows the control byte or any optional offset
byte(s). If the first optional replacement count byte has a value of 255, a second optional replacement count
byte follows the first optional replacement count byte. Optional replacement count bytes will continue until
the value becomes less than 255.
