Signal selected by 28.11 Frequency ref1 source
frequency reference 1 as such (no function applied).
The sum of the reference sources is used as frequency
reference 1.
The subtraction ([28.11 Frequency ref1
Frequency ref2 source]) of the reference sources is used as
frequency reference 1.
The multiplication of the reference sources is used as
frequency reference 1.
The smaller of the reference sources is used as frequency
reference 1.
The greater of the reference sources is used as frequency
reference 1.
Configures the selection between frequency references 1
and 2. See diagram at 28.11 Frequency ref1

Frequency reference 1 is used when external control
location EXT1 is active. Frequency reference 2 is used when
external control location EXT2 is active.
