Setting line output level
The audio level can be set by selecting the external filter components connected to the emphasis noise reduction
pins 24 and 32 (pins EMPHL and EMPHR).
Table 40
Component values for setting the line output level
Note
1.
Standard 50 kHz FM deviation at f = 1 kHz.

Test modes
Special test modes are implemented for testing, evaluation and measurement purposes. These test modes are available
when bit TEST = 1 and the test select function is enabled via five bits of the select byte (see Table 41). When selecting
test modes the normal input level setting is changed as defined by bits NIL3 to NIL0. Calibration may be lost when a not
listed test mode is selected.
