Test mode
(1) External input mode
Mode in which external 4-MHz reference signal is input. Even if a crystal resonator is connected, it
cannot operate.
(2) Internal oscillation mode
Mode in which 4-MHz crystal resonator is connected and reference signal is generated.
As with Toshiba TA1297 Series devices, an external reference signal can be input by using a resistor
to pulling up the crystal oscillator pin.
(3) Test mode
Usually, this mode is not used.
