A-D disconnection detection assist function enable bit
1: Enable A-D disconnection detection assist function
Note 1: For the A-D disconnection detection assist function to be enabled, the conversion start state (discharge or precharge) must
be set using the A-D disconnection detection assist method select register after setting the ADDDAEN bit to "1".
The A-D Disconnection Detection Assist Function Control Registers are used to enable or disable the content of
the A-D Disconnection Detection Assist Method Select Register.
Note: • If any analog input wiring is disconnected, the conversion result varies depending on the circuits
fitted external to the chip. This function must be fully evaluated in the actual application system
before it can be used.
