Read128 and Read128c
The read128 command can read the full page of the memory. Read128c addresses a page in
the control memory. Short, long, and symbolic addressing modes are supported. After receiving
the header, the command, the parameters, and, optionally, the address field, the tag expects the
CRC stream (inverted CRC), and then the two EOF symbols.
After getting the two EOF symbols the tag expects the return header. Then the tag transfers the
status2 register and the 128-bit + 16-bit CRC data back.
After transmitting the last bit, the tag expects the two EOF symbols. If it does not receive them, it
assumes that the reader is transmitting a new header. The tag enters the loop status.
The command byte is
Table 10-4.
Table 10-5.
When using long addressing modes, the page address is stored at address(2:0). The other bits
of the address field shall be set to “0”.
The start address of the block is stored at parameter(4:3). Parameter(5) shall be set to “0”.
