Universal counter input
The input must be capacitor coupled.
The input frequency range is from 0.4 to 12 MHz.
This input can be effectively used for FM IF or AM IF counting.
Universal counter input
The input must be capacitor coupled for input frequencies in
the range 100 to 150 kHz.
Capacitor coupling is not required for input frequencies from
1 Hz to 20 kHz.
This input can be effectively used for AM IF counting.
A/D converter input
A 1.28 ms period is required for a 6-bit sequential comparison
conversion. The full scale input is ((63/96) · V
DD
) for a data
value of 3FH.
External interrupt request input
An interrupt is generated when the INTEN flag is set (by an
SS instruction) and a falling edge is input.
Reference frequency and programmable divider phase
comparison error outputs
Charge pump circuits are built in.
EO1 and EO2 are the same.
Input pin used to determine if a power outage has occurred in
BACKUP mode
This pin can also be used as a normal input port.
Input pin used to force the ICs to HOLD mode
The IC goes to HOLD mode when the HOLDEN flag is set (by
an SS instruction) and the HOLD input goes low.
A high-breakdown voltage circuit is used so that this input can
be used in conjunction with the normal power switch.
System reset input
This signal should be held low for 75 ms after power is first
applied to effect a power-up reset.
The reset starts when a low level has been input for at least
six reference clock cycles.
Crystal oscillator connections
(4.5 MHz)
A feedback resistor is built in.
LSI test pins. These pins must be connected to V
SS
.
