When the AD conversion is completed, the result is loaded into the ADDATA1H. The
ADRUN bit is cleared, and the ADIF (see Section 6.1.14, RE (Interrupt Status 2 &
Wake-Up Control Register)) is set.

NOTE
■ RE <5> can be cleared by instruction but cannot be set.
■ IOCE0 is the interrupt mask register.
■ Reading RE will result to "logic AND" of RE and IOCE0.
Bit 7 & Bit 6:
Bit 5 (ADIF):
Not used
Interrupt flag for analog to digital conversion. Set when AD
conversion is completed. Reset by software
0 = no interrupt occurs
1 = interrupt request
Bit 4 :
Not used, fixed to “0”
Bit 3 (ADWE): ADC wake-up enable bit
0 = Disable ADC wake-up
1 = Enable ADC wake-up
When AD Conversion enters sleep mode, this bit must be set to
“Enable.“
Bit 2 (CMPWE): Not used, fixed to “0”
