1. A/D0 starts the A/D conversion when the ADST bit is set to "1" (A/D conversion started) and a trigger is generated.
2. The A/D conversion is restarted if an external trigger or a hardware trigger is inserted during the A/D conversion.

The BITS bit in the AD0CON1 register determines the resolution. When the BITS bit is set to "1" (10-bit
precision), the A/D conversion result is stored into bits 9 to 0 in the AD0j register (j = 0 to 7). When the
BITS bit is set to "0" (8-bit precision), the A/D conversion result is stored into bits 7 to 0 in the AD0j
register.
When the SMP bit in the AD0CON2 register is set to "1" (with the sample and hold function), A/D conver-
sion rate per pin increases to 28 Ø
The sample and hold function is available in all operating modes. Start the A/D conversion after selecting
whether the sample and hold function is to be used or not.
The TRG bit in the AD0CON0 register and the TRG0 bit in the AD0CON2 register select the trigger to
start the A/D conversion. Table 17.9 lists settings of the trigger select function.
DMAC operating mode is available with all operating modes. When the A/D converter is in multi-port
single sweep mode or multi-port repeat sweep mode 0, the DMAC operating mode must be used. When
the DUS bit in the AD0CON3 register is set to "1" (DMAC operating mode enabled), all A/D conversion
results are stored into the AD00 register. DMAC transfers data from the AD00 register to any memory
space every time an A/D conversion is completed in each pin. 8-bit DMA transfer must be selected for 8-
bit resolution and 16-bit DMA transfer for 10-bit resolution. Refer to 12. DMAC for instructions.
