Clone IC ATMEGA861V Code

We can Clone IC ATMEGA861V Code, please view the IC ATMEGA861V features for your reference:

A 50% duty cycle clock can be programmed to come out on P1.0, as shown in Figure 5. This pin, besides being a regular I/0 pin, has two alternate functions. It can be programmed to input the external clock for Timer/Counter 2 or to output a 50% duty cycle clock ranging from 61 Hz to 4 MHz at a 16 MHz operating frequency when clone ic code.

To configure the Timer/Counter 2 as a clock generator, bit C/T2 (T2CON.1) must be cleared and bit T2OE (T2MOD.1) must be set. Bit TR2 (T2CON.2) starts and stops the timer if clone ic code.

The clock-out frequency depends on the oscillator frequency and the reload value of Timer 2 capture registers (RCAP2H, RCAP2L), as shown in the following equation before clone ic code.

In the clock-out mode, Timer 2 rollovers will not generate an interrupt. This behavior is similar to when Timer 2 is used as a baud-rate generator. It is possible to use Timer 2 as a baud-rate generator and a clock generator simultaneously after clone ic code.

Note, however, that the baud-rate and clock-out frequencies cannot be determined independently from one another since they both use RCAP2H and RCAP2L when clone ic code.

The UART in the AT89S53 operates the same way as the UART in the ATMEGA861V. For fur- ther information, see the October 1995 Microcontroller Data Book, page 2-49, section titled, “Serial Interface.” if clone ic code

The serial peripheral interface (SPI) allows high-speed synchronous data transfer between the ATMEGA861V and peripheral devices or between several ATMEGA861V devices before clone ic code.

The AT89S53 SPI features include the following:

  • Full-Duplex, 3-Wire Synchronous Data Transfer
  • Master or Slave Operation
  • 1.5-MHz Bit Frequency (max.)
  • LSB First or MSB First Data Transfer
  • Four Programmable Bit Rates after clone ic code
  • End of Transmission Interrupt Flag
  • Write Collision Flag Protection
  • Wakeup from Idle Mode (Slave Mode Only)
