(b) Used Memory Capacity of QR Code
The total empty area of area1 to 3 shown in Table 6-6 is necessary for QR Code print.
For an example, when number of bar code data byte=30, model=2, and version=4;
Area1 = 30

2+560 = 620 bytes
Area2 = 8006 bytes
Area3 = 33

int
[

7 + 33
]

3+1 = 496 bytes
Total = 9122 bytes
(Empty area size is even number of bytes)

*1: N: Number of bar code data
When empty capacity of the external RAM is an odd number, one more byte is necessary.
When number of bar code data byte is an odd number, one more byte is necessary.
*2: M: Number of modules for one side of the QR Code.
V: Version
The int () means that less than a decimal point will be omitted.
When area 3 becomes an odd number, one more byte is necessary.
