How to test the Successive Approximation Type A/D Converter
23.3.2
Follow this procedure to check if the successive approximation type A/D converter works correctly. (n=0 to 15)
(1)
Enable the internal referece voltage and choose VDD for the reference voltage (VREFCON = 0x01).
(2)
A/D convert AINn pin. (conversion result 1)
(3)
A/D convert AIN=full scale by setting the SADTMOD register (SADTMOD=0x01).
(4)
A/D convert the AINn pin. (conversion result 2)
(5)
A/D convert AIN=zero scale by setting the SADTMOD register (SADTMOD=0x02).
(6)
A/D convert the AINn pin. (conversion result 3)
(7)
A/D convert AIN=internal reference voltage(approx.1.55V) by setting the SADTMOD register (SADTMOD=0x03).
(8)
A/D convert the AINn pin. (conversion result 4)
(9)
Confirm conversion result 1 = conversion result 2 = conversion result 3 = conversion result 4.
Use the same AINn pin for the A/D conversion in (2), (4), (6) and (8).
(10)
Confirm the conversion result in (3), (5) and (7) is different each other and also different from the result in (2), (4),
(6) and (8).
