Functional Description
Execution Flow
The system clock for the HT23B60 is derived from a
32768Hz crystal oscillator. A built-in frequency up con-
version circuit provides dual system clock, namely
32768Hz and 3.58MHz. The system clock is internally
divided into four non-overlapping clocks. One instruc-
tion cycle consists of four system clock cycles.
Instruction fetching and execution are pipelined in such
a way that a fetch takes one instruction cycle while de-
coding and execution takes the next instruction cycle.
However, the pipelining scheme causes each instruc-
tion to effectively execute within one cycle. If an instruc-
tion changes the program counter, two cycles are
required to complete the instruction.
Program Counter
PC
The 13-bit program counter (PC) controls the sequence
in which the instructions stored in program ROM are ex-
ecuted.
After accessing a program memory word to fetch an in-
struction code, the contents of the program counter are
incremented by 1. The program counter then points to
the memory word containing the next instruction code.
When executing a jump instruction, conditional skip ex-
ecution, loading PCL register, subroutine call, initial re-
set, internal interrupt, external interrupt or return from
subroutine, the PC manipulates the program transfer by
loading the address corresponding to each instruction.
