Circuit configuration
Note
32 kHz oscillator
5 kHz oscillator
38 kHz oscillator
The resistor Rd (200 k
typical) for use with a
32 kHz oscillator is built in.
The cycle time is four times n times the f1
period. (Note: n is 2.)
The divider outputs (1 to 15) are used as
the time base, the LCD drive waveform
generation clock, the S and K port
chattering rejection clock and for other
functions.
OSC1 is stopped when a SLOW instruction
is executed.
Option
Circuit configuration
Note
Selection of either the
Built-in pull-up
resistor, or the
Built-in pull-down
resistor option
Selection of high or
low level hold
transistor
The following ports are switched at the same
time
S1 to S4, K1 to K4, M1 to M4, P1 to P4 SO1
to SO4 and A1 to A4
At reset: The resistors are on during the reset
period.
The resistors are turned off when
reset is cleared.
Options: Either A or B can be selected.
One of A and B must be selected.
When the hold transistors used option is
selected:
Used to reduce the current flowing in the
pull-up or pull-down resistors when, for
example, a push switch is used for S1 or a
slide switch is used for S2.
For input open specification versions, the
resistors are turned on before the input is
read, the input state is read and then the
resistors are turned off. If the input is
floating at this point the high or low level
hold transistor operates to hold the value
read.
When the hold transistors unused option is
selected:
Use with the pull-up or pull-down resistor in
the on state.
Select hold transistors unused when
connecting to external control signals and
the connections will never be floating
