Unlock MCU ATMEGA1284V Heximal

We can Unlock MCU ATMEGA1284V Heximal, please view the MCU ATMEGA1284V features for your reference:

This bit is set (one) when an ADC conversion completes and the data registers are updated. The ADC Conversion Complete Interrupt is executed if the ADIE bit and the I-bit in SREG are set (one) when unlock mcu heximal.

ADIF is cleared by hardware when executing the corresponding interrupt handling vector. Alternatively, ADIF is cleared by writing a logical “1” to the flag if unlock mcu heximal.

Beware that if doing a read-modify-write on ADCSR, a pending interrupt can be disabled. This also applies if the SBI and CBI instructions are used before unlock mcu heximal.

· Bit 3 – ADIE: ADC Interrupt Enable

When this bit is set (one) and the I-bit in SREG is set (one), the ADC Conversion Complete Interrupt is activated.

· Bits 2..0 – ADPS2..ADPS0: ADC Prescaler Select Bits

These bits determine the division factor between the CK frequency and the input clock to the ADC.  When an ADC conversion is complete, the result is found in these two registers after unlock mcu heximal.

When ADCL is read, the ADC Data Register is not updated until ADCH is read. If the result is left adjusted and no more than 8-bit precision is required, it is sufficient to read ADCH when unlock mcu heximal.

Otherwise, ADCL must be read first, then ADCH. The ADLAR bit in ADMUX affects the way the result is read from the registers. If ADLAR is set, the result is left-adjusted if unlock mcu heximal.

If ADLAR is cleared (default), the result is right-adjusted.

· ADC9..0: ADC Conversion Result

These bits represent the result from the conversion. For the differential channel, this is the value after gain adjustment, as indicated in Table 20 on page 47. For single-ended conversion, or if ADLAR or SIGN is zero, $000 represents ground and $3FF represents the selected reference voltage minus one LSB before unlock mcu heximal.

Since change of analog channel always is delayed until a conversion is finished, the Free Running mode can be used to scan multiple channels without interrupting the converter after unlock mcu heximal.

Typically, the ADC Conversion Complete Interrupt will be used to perform the channel shift. However, the user should take the following fact into consideration when unlock mcu heximal:

The interrupt triggers once the result is ready to be read. In Free Running mode, the next conversion will start immediately when the interrupt triggers. If ADMUX is changed after the interrupt triggers, the next conversion has already started, and the old setting is used if unlock mcu heximal.
