Report item – opens in a new window or tab. Since the prescaler output is synchronized with the internal clocks, there is a small delay from the time the external clock edge occurs to the time l Timer0 module is actually incremented.

Provides translation of Assembler source code to object code for all Microchip microcontrollers. The 74AS04 inverter performs the degree phase shift that a parallel oscillator requires.

The ALU is 8-bits wide and capable of addition, subtraction, shift and logical operations. The instruction fetch and execute are pipelined such that fetch takes one instruction cycle while decode and execute takes another instruction cycle.

Thus, a prescaler assignment for the Timer0 module means that there is no prescaler for the WDT, and vice-versa. Also, cf74-04 the Electrical Speci? The EPROM technology makes customizing application programs transmitter codes, motor speeds, receiver frequencies, etc. For very high Rext values e. The prescaler may be used by either the Timer0 module or the Watchdog Timer, but not both.


A ‘1’ from a TRIS register bit puts the corresponding output driver in a hi-impedance mode. The item you’ve selected was not added to your cart. Please list the following information, and use this outline to provide us with your comments about this Data Sheet. A simple serial interface allows the user to construct a hardware demultiplexer for the LCD signals. Clock input to Timer0. Only the low order 4 bits are used RA3: Have one to sell? The synchronization of T0CKI with the internal phase clocks is accomplished by sampling the prescaler output on the Q2 and Q4 cycles of the internal phase clocks Figure pp All instructions are executed within one single instruction cycle, unless a conditional test is true or the program counter is changed as a result of an instruction.

Stresses above those listed under “Maximum Ratings” may cause permanent damage to the device. What sets a microcontroller apart from other processors are special circuits that deal with the needs of real-time applications. We want you as our fully satisfied customer.


Also, there is a delay in the actual incrementing of Timer0 after cf745-40. The Timer0 module has the following features: The special registers can be classi? If ‘d’ is 1 the result is stored back in register ‘f’.

Z The contents of register ‘f’ are complemented. Learn more – opens in a new window or tab. Two types of crystal oscillator circuits can be used: In some o or tables the data presented are outside speci? None The eight bit literal ‘k’ is loaded into the W register. Seven or eight special function hardware registers?


If a conditional test is true or the program counter is changed as a result of an instruction, the instruction execution time is 2? External clock if no prescaler selected, Prescaler output otherwise.
