Description
Serial/ parallel (SP/ LP) mode
switching pin. When this pin
is 4.3V or more, the IC
SP/LP

PLL time constant pin. Since
this pin has a small attraction
and discharge current,
signals should be received
with high impedance when
monitoring this pin. Also, be
careful not to cause pin cross
talk.
