3.0 FUNCTION DESCRIPTION
INT0 ~ INT2 are the interrupt input pins that will be mapped to the dedicated sector
according to the corresponding pin name. These pins are applied with different priority
according to the corresponding pin number when more than 2 pins inputting
simultaneously.
OUT0 ~ OUT1 are the general-purpose output signal to either generate the stop
signal or to drive the LED device.
The LED output signal has 4 programming modes: flash mode, DC mode (always
ON) , or 2Hz flash or flash with speech(pulse width 100ms) or flash with speech
volume.
The OSCI & OSCO are designed to be connected with a resistor. The operational
frequency ranges around 1 MHz.
TEST will only be activated when testing is in progress.Pull down this pin can switch
the INTA and OUT pins as the data bus to dump the internal test patterns.
VDD can be applied to range from 2.4 to 5.0 V for proper operation.
VSS is normally tied to the system Ground.
4.0 MATRIX KEY-PAD ARRANGEMENT
The input can be designed up to 9 keys by implementing the matrix mechanism.
Power-ON initialization operation initiates INTA = 0x0F, OUT = 0x0 to detect the falling
edges of trigger inputs (INT0 ~ INT2).
