Function
• Input/output shared-function pins
• In output mode, the circuits are complementary outputs.
• The I/O direction is determined by I/O-4 and I/O-5 in the serial data.
When the data is 0: input port
When 1: output port
• When specified for use as input ports
The input pin states are transmitted from the DO pin to the controller
Input state = low : Data = 0
Input state = high : Data = 1
• When specified for use as output ports
The output states are determined by OUT4 and OUT5 in the serial data.
Data = 0 : low
Data = 1 : high
• These pins are set to function as input ports by the power-on reset.
Pin circuit
7
O-6 Output port
• The OUT6 bit in the serial data is latched and output from O-6.
• The OUT7 bit in the serial data is latched and output from O-7.
6
O-7 Output port
• This pin outputs the 8 Hz clock time base signal when TBC is 1.
• This pin is set to the open state by the power-on reset.
• PLL charge pump output pins
When the frequency created by dividing the local oscillator signal
20
PD0 Charge pump
frequency by N is higher than the reference frequency, a high level is
19 PD1 output
output from the PD0 pin, and when lower, a low level is output. When the
frequencies match, PD0 goes to the high-impedance state.
• PD1 operates in a similar manner.
• HCTR is selected when CTS1 in the serial data input is set to 1.
—The input frequency range is 0.4 to 25 MHz
—The signal is passed through an internal divide-by-two circuit and
transmitted to a general-purpose counter. An integrating count can also
be performed.
14
HCTR/I-6
General-purpose
counter
—The result is output starting with the MSB of the general-purpose
counter from the DO pin.
—There are four counting time periods: 4, 8, 32, or 64 ms.
—See the item on the general-purpose counter for details.
• When H/I-6 in the serial data is set to 0
— This pin functions as an input port, and its state is output from the DO
output pin.
• LCTR is selected when CTS1 in the serial data input is set to 0.
• When CTS0 in the serial data input is set to 1 in the CTS1=0 state.
—The circuit operates in frequency measurement mode.
—The input frequency range is 10 to 500 kHz.
—The signal is transmitted directly to the general-purpose counter.
• When CTS0 in the serial data input is set to 0
—The circuit operates in period measurement mode.
13
LCTR/I-7
General-purpose
counter
—The input frequency range is 1 Hz to 20 kHz.
—The measurement period can be set to be either 1 period or 2 periods.
If 2-period measurement is selected, the input frequency range will be
2 Hz to 40 kHz.
—The result is output starting with the MSB of the general-purpose
counter from the DO pin.
—See the item on the general-purpose counter for details.
• When L/I-7 in the serial data input is set to 0.
—This pin functions as an input port, and its state is output from the DO
output pin.
