7.1 Preset Memory Read
The specified preset memory is read when any of the
than 2 seconds while in tuner mode with initial setting diode MESEL = 0, or when any of the
keys is pressed in a mode other than memory write enable mode with MESEL = 1.
A mute timing diagram showing the preset memory read operation is given below.
