Reset Mode
Pulling the XRESET pin low for more than 2 mS places the W93902 in reset mode, which causes all
configurations to be cleared. To release the configuration mode, let the XRESET pin return to high for
2 mS. The W93902 will then automatically enter Txclk wait mode, and so another 128 Txclk are
needed. If the XRESET pin is low for more than 2 mS and the ON pin is high, the chip enters board
test mode.
Board Test Mode
To place the W93902 in board test mode, set the ON pin high in reset mode. In board test mode BS1
and BS3 remain high until the ON pin returns to low. When the XRESET pin returns to high, the
W93902 exits both board test mode and reset mode. Board test mode is usually used for the RF
adjust function. When in board test mode, the NRZIN signal will output to FALM pin, so that we can
trim the RF trimmer by buzzer frequency.
