General Description of Function
1.
Oscillator
Since a self-bias type amplifier of CMOS inverter is contained, an oscillator can be formed by connecting a ceramic
resonator.
To minimize power dissipation, the oscillator stops oscillating except when key operation is performed.
2.
Key entry
Key entry pins K
I
0 to K

7 provide a key matrix of 4
×
8 = 32.
Multi-press of key No. 20 and one of key No. 21, 22, 23 may be done, with no priority given in key entry. When the two
keys are kept pressed, a series of pulses will be output according to each key entry. If multi-press of keys which are not
allowed multi-press is done, no output will be delivered.
3.
Data organization
Data consists of 42 bits in all: 13 bits of custom code, 8 bits of key data, and their inverted codes.
