... Function Description Execution Flow The system clock for the HT36FA is derived from either a crystal oscillator. The oscillator frequency di- vided the system clock for the MCU ( and it is internally divided into four OSC SYS non-overlapping clocks. One instruction cycle consists of four system clock cycles ...

... Wavetable ROM The ST12~ST0 is used to defined the start address of each sample on the wavetable and read the waveform data from the location. HT36FA provides 18 output ad- dress lines from WA17~WA0, the ST12~ST0 is used to locate the major 13 bits i.e. WA17~WA5 and the unde- fined data from WA4~WA0 is always set to 00000b. So the start address of each sample have to be located at a multiple of 32 ...

... CALL subroutine operates in the interrupt subroutine, it may damage the original control sequence. Oscillator Configuration The HT36FA provides two types of oscillator circuit for the system clock e., RC oscillator and crystal oscillator. No matter what type of oscillator, the signal divided used for the system clock (f mode stops the system oscillator and ignores external signal to conserve power ...

... For example, the SET [m].i , CLR [m].i , CPL [m] and CPLA [m] instructions read the entire port states into the CPU, execute the defined op- erations (bit-operation), and then write the results back to the latches or the accumulator. Each line of port A has the capability to wake-up the device. 13 HT36FA Timer 0/1 February 26, 2007 ...
