Device Functions
Example: 17 bytes should be written starting at address 187. Data carrier = 32 bytes per block.
Blocks 5 and 6 are processed, since the start address 187 is in block 5 and end address 203 is
in block 6.
t = 2 * 120 + 17 * 10 = 410

m = Highest address to read
Formula: t = (m + 1) * 3.5 ms
Example: Read 11 bytes starting at address 9. This means that the largest address to be read is
19. This yields 70 ms.
Dynamic operation with BIS C: The times indicated apply after the data carrier has
been detected. Otherwise 45 ms must be added for powering up until the data carrier
is recognized. To achieve the read times specified in dynamic operation, the Tag Type
parameter has to be set to "BIS C 32 Byte" or "BIS C 64 Byte" on the respective
head.
