FUNCTION
Power supply pins. The VM pin applies a positive supply with respect to the GND.
LSI chip test pins. Cannot be used by the user. Connect T and T2 pin to GND.
Connect T1 pin to VM.
Input pin with built-in pull-up resistor. Hardware reset the LSI chip when a LOW level
signal is input. Normally a capacitor is connected between it and GND to form a pow-
er-on reset circuit.
CR or crystal oscillator pins. Connect a CR or crystal oscillating element across
OSCIN - OSCOUT (crystal) or OSCIN - CK2 (CR) to form a clock generator circuit.
Use of a CR or crystal oscillating element is determined by the mask option.
Melody output pin. Outputs the contents of a melody ROM with 12 musical scale
(555 to 2,114 Hz) in two octaves.
Common output pins. Pins for the LCD’s common signals.
Pins for the LCD’s segment signals.
Input pin for external interrupt. The IFA flag is set at the leading edge of INTA.
Output pins. The accumulator ACC can be transferred to this port by instruction.
I/O pins which can switch to input or output pins in 4-bit units by instruction. They
can be used as output pins when configured for a key matrix. The SM5Lx is forced
to hardware reset when all of P10 - P13 pins are HIGH level (by mask option).
