lsi LS3201 2 functional description 1. rc oscillator /crystal the LS3201 can use either a crystal oscilla tor or rc oscillator to provide the internal timing by mask option. 2. program rom the lsi3201 has internal 2kx12 bit rom provid ing simple operation. it has four internal stack. 3. interrupt control the lsi3201 has 5 different sources of interru pt, namely, powerup, f4hz, f16hza, f16hzs and f1hz. the starting address of the interrupt ar e as follow : interrupt address powerup 0 f1hz 1 f4hz 2 f16hza 3 f16hzs 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.
