Beyond the above
Disable settings.
Note 1. When scanning mode, bit4, bit5 and bit6 must be set to 0.
2. For ports that are set as analog inputs by the PMCx register, A/D conversion can only be specified as analog inputs
by ADS.
3. Pins set to digital input/output by the port-mode control register (PMC xx) cannot be set through the ADS register.
4. To override the ADISS bit, it must be done in the transition stop state (ADCS=0, ADCE=0).
5. After setting the ADISS bit to 1, the result of the first conversion cannot be used.
6. The ADISS bit cannot be set to 1 when shifting to deep sleep mode or when shifting to sleep mode while the CPU is
running on the subsystem clock.
