SCL010/01X REFERENCE MANUAL 48
Example
For an NFC forum tag type 1 which has the following memory dump
The following sequence does
A READ of the byte # 0x03 in block 0x07
A WRITE NO ERASE of the byte # 0x03 in the block
=0x07 with value 0x09
A READ of the byte # 0x03 in block 0x07
One can notice that the value of the byte after the WRITE NO
ERASE is not 0x09 but 0x0B because the memory value before the
operation was 0x02. The memory result of a WRITE NO ERASE
command is the logical OR of the value before the operation and
the value written:
description Value (binary) Value (0x)
Memory value before (00000010)b 0x02
Value written (00001001)b 0x09
Result (00001011)b 0x0B
