1.7.11 INTERNAL VOLTAGE REGULATOR
There are separate Analog and Digital regulators in the ZIC2410. The Analog regulator
supplies power to the RF and analog blocks, while the Digital regulator supplies power to all the
digital blocks. MSV, an external pin, sets the output voltage: when MSV is set to ‘0’, 1.5V is
generated and when MSV is set to ‘1’, 1.8V is generated. AVREG3V and DVREG3V, external
pins, should be connected to the 3V supply in order to operate the internal regulators.

Quad Enable. When this field is set to ‘1’, the Quad Decoder is
enabled.
Quad Initialize. When this field is set to ‘1’, the internal register
values of the Quad Decoder are initialized.
Mode Select. When this field is set to ‘1’, counter value is
increased to the point of changing movement direction. When this
field is set to ‘0’, current counter value is decreased to the point of
changing movement direction.
