(7) Next, bit 8 of the successive approximation register (SAR) is automatically set, and the next comparison is
(8) When comparison of 10 bits has been completed, the valid digital value result remains in the successive
started. The voltage tap of the array is selected according to the value of bit 9, to which the result has been
already set.
The voltage tap of the array and the analog input voltage are compared and bit 8 of the SAR is manipulated
according to the result of the comparison.
Comparison is continued like this to bit 0 of the SAR.
approximation register (SAR). This value is transferred to A/Dn conversion result register m (ADAnCRm) and
the conversion result is stored in this register (n = 0, 1, m = 0 to 3). When A/D conversion has ended the
specified number of times, an A/Dn conversion end interrupt request signal (INTADn) is generated.
Bit 9 = 0: (1/4 AV
Bit 9 = 1: (3/4 AV
Analog input voltage ≥ Voltage tap of array: Bit 8 = 1
Analog input voltage ≤ Voltage tap of array: Bit 8 = 0
