(10) Next, bit 10 of the successive approximation register (SAR) is automatically set, and the next comparison is
(11) When comparison of 12 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 11, to which the result has been
already set.
The voltage tap of the array and the analog input voltage are compared and bit 10 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 (ADnCRm) and
the conversion result is stored in this register in the A/D trigger mode, A/D trigger polling mode, hardware
trigger mode, and conversion channel specification mode (n = 0, 1, m = 0 to 15). The valid digital value is
stored in the A/Dn conversion result extension buffer register a in the extension buffer mode, and is shifted to
A/Dn conversion result extension register a when selection load trigger x is generated and stored (x = 1, 2, a =
0 to 4). When A/D conversion has ended the specified number of times, an A/Dn conversion end interrupt
request signal (INTADn) is generated.
