CHAPTER 15 8/10-BIT A/D CONVERTER
15.6 Registers
[bit3] ADI: Interrupt request flag bit
This bit detects the completion of A/D conversion.
When the A/D conversion function is used, the bit is set to "1" immediately after A/D conversion is
complete.
Interrupt requests are output when this bit and the interrupt request enable bit (ADC2: ADIE) are both set to
"1".
When "0" is written to this bit, it is cleared. Writing "1" to this bit does not change it or affect other bits.
When read by the read-modify-write (RMW) type of instruction, this bit always returns "1".
[bit2] ADMV: Conversion flag bit
This bit indicates that A/D conversion is in progress.
The bit is set to "1" during A/D conversion.
This bit is read-only. Writing a value to this bit has no effect on operation.
[bit1] Reserved bit
Always set this bit to "0".
[bit0] AD: A/D conversion start bit
This bit starts the A/D conversion function with the software.
Writing "1" to the bit starts the A/D conversion function.
When the continuous start enable bit in the ADC2 register (ADC2:EXT) is "1", starting the A/D conversion
with this bit is disabled.
With the EXT bit set to "0", when "1" is written to this bit while A/D conversion is in progress, A/D
conversion restarts.
Note: Writing "0" to this bit cannot stop the operation of the A/D conversion function. The read value of this
bit is always "0".
bit3 Details
Reading "0" Indicates that A/D conversion has not been completed.
Reading "1" Indicates that A/D conversion has been completed.
Writing "0" Clears this bit.
Writing "1" Has no effect on operation.
bit2 Details
Reading "0" Indicates that A/D conversion is not executed.
Reading "1" Indicates that A/D conversion is in progress.
bit0 Details
Writing "0" Has no effect on operation.
Writing "1" Starts the A/D conversion function.
