8.8.1
This command is used to read the demodulated bit stream from a transponder.
After the assertion of the three command bits the HTRC11001T instantaneously switches to the READ_TAG mode and
transmits the demodulated, filtered and digitized data to the microcontroller. This data should be decoded by the
microcontroller.
The READ_TAG mode is terminated by a LOW-to-HIGH transition on pin SCLK.
8.8.2
This command is used to write data to a transponder.
If bits N3 to N0 are set to 0000, the signal on pin DIN is transparently switched to the drivers. A HIGH level on pin DIN
corresponds to antenna drivers switched off and a LOW level corresponds to antenna drivers switched on.
For any binary number N between 0001 and 1111, the drivers are switched off at the next positive transition on pin DIN.
This state is held for a time interval t = N
the microcontroller and to the software implementation while providing an exact, selectable write pulse timing.
The WRITE_TAG mode is terminated immediately by a LOW- to-HIGH transition on pin SCLK.
