Functional Description
1. RC Oscillator /Crystal
The LS3201 can use either a crystal oscillator or RC oscillator to provide the internal timing by
mask option.
2. Program ROM
The LSI3201 has internal 2Kx12 bit ROM providing simple operation. It has four internal stack.
3. Interrupt Control
The LSI3201 has 5 different sources of interrupt, namely, POWERUP, F4HZ, F16HZA, F16HZS
and F1HZ. The starting address of the interrupt are as follow :
Interrupt
POWERUP
F1HZ
F4HZ
F16HZA
F16HZS
Address

4
The system generates 16 interrupts for F16HZS in one second but only 11 interrupts for F16HZA.
The other 5 interrupts goes to F4HZ (4) and F1HZ (1) interrupts.

4. Buzzer Control/Tone Generator Control
The system can output 4khz/2khz alarm signal by mask option. The alarm signal is enabled to the
output BD[0:1] when the Beep Control Register: Bit[0] is high.
Tone Control Registers (70H – 72H) is used to control the Tone Generator to generate music tone
signal at the buzzer output pad B0, B1.
5. LCD driver
The system has 28 LCD segment pad with 2/3/4 common pads (mask option) providing 28x2, 28x3
LCD segment output.
The LCD segment table is shown below :
