INFS
Tag Data Information Set
Opcode:
0x3D
Syntax:
INFS data_offsett Num_Of_Bytes byte
1.
..byte
n
Type:
Synchronous
Description:
Resets the data information in the tag header, starting from offset
data_offsett
of
the current message, for length of Num_Of_Bytes bytes.
Note: the data in the Flash memory is set to FF and, by writing to it, the data is
changed to 0. After resetting a bit in the Flash, you cannot set it to 1. (The
memory is set back to FF after the erasing procedure).
Parameters:
data_offsett and Num_Of_Bytes are one byte long. The maximum number of
bytes that can be stored in a message header is 74. This means:
74>(data_offsett + Num_Of_Bytes).
