I/O
I
Crystal resonator connection.
I
Chip enable.
I
Input serial data.
Used as the synchronization clock when serial data is input to the DI(pin 3), or
I
when serial data is output DO(pin 5).
O
Outputs serial data.
• Dedicated output pins.
• The output states are determined by B01 to B04 in the serial data.
O
"Data" =0 : Open "Data" =1 : Low
• These pins go to the open state after the power-on reset.
Pins used for both input and output.
I/O The input or output state is determined by bits I0C1and I0C2 in the serial data.
"Data" = 0 : Open, "Data" = 1: Low
I
IF count input.
I
Local oscillator signal input.
I
Local oscillator signal input.
-
Power supply.
O
PLL charge pump output
I
The MOS transistor used for the PLL active low-pass filter.
O
-
Ground.
