When it is high, the 16.9344-MHz crystal oscillator (XI, XO) starts operating. The controller counts clock pulses from this oscillator and waits a specified standby time (approximately 50 ms) before starting the controller program from address 0. The CD processor is placed in the standby state at this time. MVDD MVSS Normally, raising the voltage on MVDD from 0 to 1.8 V or higher triggers a system reset (power-on reset) so that the RESET pin should be held at high. MVDD 2-bit CMOS I/O port. Input/output can be specified for each bit. When the pins are used as I/O port input, each pin can be pulled up or down by program. When backup release for clock stop mode or wait mode is enabled for the pins, a change in a pin can release the backup state. 50 51 P8-0 /MXI /OSC (BRK1) P8-1 /MXO (BRK2) I/O port 8-0 /crystal oscillator /CR oscillator I/O port 8-1 /crystal oscillator The program can set these pins to be used for a 75-kHz or 32.768-kHz dedicated crystal oscillator. The P8-0 pin can also be used for a CR oscillator. These clocks are used for the operation of the controller and peripheral devices. Upon a system reset, the 16.9344-MHz crystal oscillator (XI, XO) is selected as the clock for controller and peripheral device operation. The program can subsequently set the pins to oscillator pins and switch the clock generated from the oscillator to the controller clock. When the pins are used for an oscillator, executing the CKSTP instruction causes its oscillation to stop. (Note) When the P8-0 pin is used for a CR oscillator, the P8-1 pin can used as an I/O port pin.

When the 1/2 bias method is set, three instruction common output levels (MVDD, 1/2MVDD and RIN2 GND) and two segment output levels (MVDD and GND) appear on the pins. When the 1/3 bias method is set, four common and segment output levels (MVDD, 1/3MVDD, 2/3MVDD and GND) appear on the pins. I/O port 3 /LCD segment output Upon a system reset or after clock stop mode is released, a non-select waveform (bias voltage) is driven and the DISP OFF bit is set to 0, after which the common signals are driven. During a system reset ( RESET = low), the TEST/P3-0/S1 pin is pulled down and accepts test mode input. This pin should be left open or applied low level during a reset. The P5-1 to P6-3 and P1-0 to P1-2 pins can be set to CD processor-dedicated pins on a per pin basis.
