R/W

Description

8-bit mantissa of channel spacing. The channel spacing is

multiplied by the channel number CHAN and added to the

base frequency. It is unsigned and has the format:

248 (0xF8)

R/W

The default values give 199.951 kHz channel spacing (the

closest setting to 200 kHz), assuming 26.0 MHz crystal

frequency.
