I/O
Pin explanation
Equivalent circuit
LCTR
71
I
Universal counter (frequency or period measurement) and general-
purpose input shared function input port.
The IOS1 instruction is used for switching between the universal
counter and general-purpose input functions.
• When used for frequency measurement :
The universal counter function is set up with the IOS1 instruction.
Set up LCTR frequency measurement mode with the UCS
instruction, and control operation with the UCC instruction.
Since this pin functions as an AC amplifier in this mode, the input
signal must be input with capacitor coupling.
• When used for period measurement :
The universal counter function is set up with the IOS1 instruction.
Set up LCTR frequency measurement mode with the UCS
instruction, and control operation with the UCC instruction.
Since the bias feedback resistor is disconnected in this mode, the
input signal must be input with DC coupling.
• When used as a general-purpose input pin :
The general-purpose input port function is set up with the IOS1
instruction.
Data is read from the port using the INR (b1) instruction.
Input is disabled in Backup mode. (The input pin will be pulled down.)
The universal counter function (HCTR frequency measurement mode)
is selected after a power on reset.
SNS
70
I
Voltage sense and general-purpose input shared function port.
This input circuit is designed with a low input threshold voltage.
• When used as a voltage sense input :
The pin is used to test for power failures on the return from Backup
mode.
Application can test this condition using the internal SNS flip-flop.
The SNS flip-flop can be tested with the TST instruction.
(This usage requires external components, capacitors and resistors.
For the sample application circuit, see the user’s manual.)
• When used as a general-purpose input port :
When used as a general-purpose input port the pin state can be
tested with the TST instruction.
Unlike the other input ports, input to this pin is not disabled in Backup
mode and after a power on reset. As a result, through currents must
be taken into account when designing applications that use this pin as
a general-purpose input.
HOLD
69
I
Power supply monitor (with interrupt function)
This is designed with a high input threshold voltage.
This pin is normally connected to the ACC line and used for power off
detection.
When a power off state is detected, the HOLDON flag and the hold
interrupt request flag will be set.
To enter Backup mode, execute a CKSTP instruction when the HOLD
pin is low. Set this pin high to clear Backup mode.
RESET
68
I
System reset pin.
When the CPU is operating or in Halt mode, the system is reset when
this pin is held low for at least one machine cycle. Execution starts
with the PC pointing to location 0. At this time the SNS flip-flop is set.
A low level must be applied for at least 50ms when power is first
applied.
