Since the external timer pins are pin-shared with other I/O pins, to ensure that these are configured to operate as pulse width measurement pins, it is only necessary to ensure that the TM1/TM0, T0M1/T0M0 or T1M1/T1M0 bits place the Timer/Event Counter in the pulse width measuring mode.

    LCD Type MCU Programming Considerations When configured to run in the timer mode, one of the internal system clock sources is used as the timer clock source and is therefore synchronized with the overall operation of the microcontroller. In this mode, when the appropriate timer register is full, the microcontroller will generate an inter- nal interrupt signal directing the program flow to the respective internal interrupt vector.

    Each device contains two interrupt control registers, known as INTC0 and INTC1, which contain the interrupt control bits which set the enable/disable and request flags of each of the individual interrupt functions. Note that as the HT49R30A-1/HT49C30-1/HT49C30L devices have only one internal Timer/Event Counter, their interrupt control register structure is different from the HT49R50A-1/HT49C50-1/HT49C50L and HT49R70A-1/HT49C70-1/HT49C70L de- vices, which have two internal Timer/Event Counters.

    In the case of Holtek microcontrollers, a comprehensive and flexible set of over 60 instructions is provided to en- able programmers to implement their application with the minimum of programming overheads.

  • Page 93: Arithmetic Operations

    The standard logical operations such as AND, OR, XOR and CPL all have their own instruction within the Holtek microcontroller instruction set. As with the case of most instructions involving data manipulation, data must pass through the Accumulator which may involve additional pro- gramming steps.

  • Page 94: Other Operations

    To overcome this problem, Holtek microcontrollers allow an area of Program Memory to be setup as a table where data can be directly stored. A set of easy to use instructions provides the means by which this fixed data can be referenced and retrieved from the Program Memory.

  • Page 110: Chapter 4 Assembly Language And Cross Assembler

    Cross Assembler Assembly-Language programs are written as source files. They can be assembled into object files by the Holtek Cross Assembler. Object files are combined by the Cross Linker to generate a task file. A source program is made up of statements and look up tables, giving directions to the Cross As- sembler at assembly time or to the processor at run time.

  • Page 111: Statement Syntax

    LCD Type MCU Example of Convention Description of Convention Three dots following an item signify that more items with the same form may be entered. For example, the directive PUB- LIC has the following form: Repeating elements... PUBLIC name1 [,name2 [,...]] In the above form, the three dots following name2 indicate that many names can be entered as long as each is pre- ceded by a comma.
