Figure 9-11. Format of Analog Input Channel Specification Register (ADS) (2/2)

Address: FFF31H

After reset: 00H

 Scan mode (ADMD = 1)

Note 32-pin products only

Cautions 1. Be sure to clear bits 3, 5, and 6 to "0".

2 Set a channel to be set the analog input by ADPC and PMC1 registers in the input mode by using

port mode register 1 (PM1).

3. Do not set the pin that is set by the A/D port configuration register (ADPC) as digital I/O by the

ADS register.

4. Rewrite the value of the ADISS bit while conversion is stopped (ADCS = 0, ADCE = 0).

5. If using AV

conversion channel.

6. If using AV

conversion channel.

7. If ADISS is set to 1, the internal reference voltage (1.45 V) cannot be used for the + side reference

voltage. After the ADISS bit is set to 1, the initial conversion result cannot be used. For the

setting flow, see 9.7.4 Setup when temperature sensor output voltage/internal reference voltage

is selected.

8. Do not set the ADISS bit to 1 when shifting to STOP mode. When the ADISS bit is set to 1, the A/D

converter reference voltage current (I

be added to the current consumption when shifting to HALT mode while the CPU is operating on

the main system clock.

9. Ignore the conversion result if the corresponding ANI pin does not exist in the product used.
