/*
SI4707_PATCH.h
Si4707 1050 Hz False Detection Patch.
Description: The device may falsely detect a 1050 Hz tone on weather band stations that
have > 5 kHz deviation.
Impact: Major – A weather alert may be triggered by regular content that is over-deviated
by the broadcaster, in some cases causing the radio to autonomously turn on.
Workaround: If 1050 Hz detection is required, it is strongly recommended that customers
issue the below initialization string after sending the powerup command (0x01) with the
argument 1, bit 5 set to 1.
