ATS 20+ PPM Correction about si4735 HOT 1 OPEN

Property 0x3104. AM_MODE_AFC_SW_PULL_IN_RANGE
Sets the SW AFC pull-in or tracking range. The value PULL_IN_RANGE is relative to the tuned frequency and is
specified as 1/(PPM×10–6). For example to program a pull-in range of 115 ppm,
PULL_IN_RANGE = 1/(115×10–6) = 8695. The command is complete when the CTS bit (and optional interrupt) is
set.
Available in: Si4734/35-C40 and later, Si4732, Si4742/43/44/45
Default: 0x21F7 (115 ppm)

Property 0x3105. AM_MODE_AFC_SW_LOCK_IN_RANGE
Sets the SW AFC lock-in or capture range. The value LOCK_IN_RANGE is relative to the tuned frequency and is
specified as 1/( PPM×10–6). For example to program a lock-in range of 85 ppm,
LOCK_IN_RANGE = 1/(85×10–6) = 11765. The command is complete when the CTS bit (and optional interrupt) is
set.
Available in: Si4734/35-C40 and later, Si4732, Si4742/43/44/45
Default: 0x2DF5 (85 ppm)

I wouldn't know how to put that in the sketch.
