Use this command to read data from the tags. Data can be read from a user-specified page.
Command
This command sends the pages to be read as command parameters. The page specification is as follows: The
bits that correspond to the pages to be read are set to 1, and all other bits are set to 0. This binary number is
converted to hexadecimal and sent with the command. The pages are specified by the user.

Response
Returns the data read and the end code (normal end: '00'). The read data is returned sequentially in
ascending order of the pages specified. If an error occurs, an error code is returned. In the case of a Tag
equipped with I-CODE1, the read data is returned in the order: B⇒C⇒D⇒E⇒F⇒0⇒1⇒···⇒A.
