A/D converter n mode register 0 (ADMn0)
The ADMn0 register is an 8-bit register that specifies the operation mode, and executes
conversion operations.
This register can be read or written in 8-bit or 1-bit units. However, bit 6 can only be read. Writing
this bit is ignored.
Reset input sets this register to 00H.
Cautions: 1. When the ADCEn bit is 1 in the timer trigger mode and external trigger mode, the
trigger signal standby state is set. To clear the ADCEn bit, write 0 or reset.
In the A/D trigger mode, the conversion trigger is set by writing 1 to the ADCEn
bit. After the operation, when the mode is changed to the timer trigger mode or
external trigger mode without clearing the ADCEn bit, the trigger input standby
state is set immediately after changing the register.
2. Changing the setting of the BSn and MSn bits is prohibited while A/D conversion
is enabled (ADCEn bit = 1).
3. When data is written to the ADMn0 register during an A/D conversion operation,
the conversion operation is initialized and conversion is executed from the
beginning.
