AD converter control register 1
ADCCR1
(0x0034)
Note 1: Do not perform the following operations on the ADCCR1 register while AD conversion is being executed
Note 2: If you want to disable all analog input channels, set AINEN to "0".
Note 3: Although analog input pins are also used as input/output ports, it is recommended for the purpose of maintaining the
Note 4: When STOP, IDLE0 or SLOW mode is started, ADRS, AMD and AINEN are initialized to "0".
Note 5: When PMD interrupt signal(INTPWM) is generated during setting <AMD> to (0y10), a desinated channel is AD converted
Note 6: After ADRS is set to "1", it is automatically cleared to "0". The time between when ADRS is set to "1" and when it is cleared
