Sample and hold is selected by setting bit 0 of the A/D control register 2 (address 0394
sample and hold is selected, the rate of conversion of each pin increases. As a result, a 28 f

modes. However, in all modes, be sure to specify before starting A/D conversion whether sample and
hold is to be used.
In one-shot mode and repeat mode, the input via the extended analog input pins ANEX
also be converted from analog to digital.
When bit 6 of the A/D control register 1 (address 0397
converted from analog to digital. The result of conversion is stored in A/D register 0.
When bit 6 of the A/D control register 1 (address 0397
converted from analog to digital. The result of conversion is stored in A/D register 1.
Set the related input peripheral function of the function select register B3 to disabled.
In this mode, multiple external analog inputs via the extended analog input pins, ANEX
be amplified together by just one operation amp and used as the input for A/D conversion.
When bit 6 of the A/D control register 1 (address 0397
output from ANEX
corresponding A/D register. The speed of A/D conversion depends on the response of the external op-
eration amp. Do not connect the ANEX
connect the pins in external operation amp mode.
Set the related input peripheral function of the function select register B3 to disabled.
