(2) Setting at least one of the INT0, INT1, and INT2, pins to the specified level
(3) Having an interrupt source established at port 0
• X'tal HOLD mode: Suspends instruction execution and the operation of the peripheral circuits except the base timer
and infrared remote controller circuit.

•Same Package and Pin Assignment as Mask ROM Version.
1) LC877600 series options can be specified by using flash ROM data. Thus the board used for mass production can
be used for debugging and evaluation without modifications.
2) If the program for the mask ROM version is used, the size of the available ROM/RAM spaces is the same as
that of the mask ROM version.

Note 6-1: The quantization error (±1/2LSB) is excluded from the absolute accuracy value. The absolute accuracy refers
to the accuracy that is measured while there is no change in the I/O state of the pins adjacent to the analog
input channel.
Note 6-2: The conversion time refers to the interval from the time the instruction for starting the converter is issued till
the time the complete digital- conversion-value corresponding to the analog input value is loaded in the
required register.

The oscillation stabilization time refers to the time interval that is required for the oscillation to get stabilized after VDD
goes above the operating voltage lower limit (see Figure 4).

The oscillation stabilization time refers to the time interval that is required for the oscillation to get stabilized after the
instruction for starting the subclock oscillation circuit is executed and to the time interval that is required for the
oscillation to get stabilized after the HOLD mode is reset (see Figure 4).
Caution: The components that are involved in oscillation should be placed as close to the IC and to one another as
possible because they are vulnerable to the influences of the circuit pattern.
