Note 1: See matching circuit parameters and antenna design guide for information, and Application Notes available
from http://www.hoperf.com.
Note 2: Using other than a 10 MHz crystal is not recommended because the crystal referred timing and frequency
parameters will change accordingly.
Note 3: During this period, commands are not accepted by the chip.
Note 4: Autocalibration can be turned off.
