This pin has two functions.
-L
1. Preset Mode: This pin will be in input mode for the
selection of the search frequency step size. A 1MΩ
resistor has to be connected from this pin to VDD or
13 14 AM_STEP I/O GND to indicate the search frequency step selection. -
(H = 9kHz step, L = 10kHz step)
-
2. Search Mode: This pin will become output mode.
Pulse will be outputted when a search frequency step,
either Upward or Downward search, is reached.
