oscillator will stop. This causes system to malfunction. In this condition, the system will initiate the
LVD circuit to generate an internal reset signal to remove the malfunction.
19.Instruction Cycle
Instructions and internal operations are executed in synchronization with the main clock. The minimum unit of
instruction is called the instruction cycle. SC73C1602 has 1 and 2-cycle OP Code instructions.
An instruction cycle consists of 5 states (STCLK1 –STCLK5). Each state consists of 1 main clock. Therefore, the
instruction cycle time is 5/fmain [s].
20.The Carrier
1. fcarry is the output carrier frequency. Fin is the input frequency of the carrier generator (a register
concerned with the settings of the carrier). It is also the oscillation frequency of the IC.
2. fcarry = Fin / ( CH+CL+2 ). For example, 38.10(105) at Fin =4000KHz, 38.10 mean the carrier
frequency that can be achieved under certain conditions, If CH + CL + 2 = 105, the generated carrier
frequency is 38.10KHz.
3. CH: the register that determines the duration of the high level carrier, the duration of the high level
carrier is: (CH + 1 ) / Fin .
4. CL: the register that determines the duration of the low level carrier, the duration of the low level carrier
is : ( CL + 1 ) / Fin .
