摘要:
In an A/D converter and a microcontroller including the same, the number of selection patterns of analog input channels is increased for each A/D conversion and the A/D conversion is conducted using an A/D converter having only fundamental functions without imposing load onto a CPU. The A/D converter or a DMA transfer device includes an A/D conversion table including one or more entries. Each entry includes enable bits for setting whether or not an A/D conversion is executed for the respective analog input channels and a plurality of count number bits for setting a number of executions of the A/D conversion.
