(a) Sample and hold
Sample and hold is selected by setting bit 0 of the A-D control register 2 (address 03D416) to “1”.
When sample and hold is selected, the rate of conversion of each pin increases. As a result, 28 φ AD
cycles are achieved with 8-bit resolution and 33 φ AD cycles with 10-bit resolution. Sample and hold
can be selected in all modes. However, in all modes, be sure to specify before starting A-D conversion
whether sample and hold is to be used.
