ADENA
Bit 0 ADENA. Enable Analog Input
The ADENA control bit configures port A0 as either an analog input
channel or a logic input channel. When the bit is set to 1, port A0 can
be enabled for analog signal input. When the bit is set to 0, port A0 can
be enabled for logic level input.
0 = Pin A0 is a digital input port
1 = Pin A0 is an analog input port.
Bit 1-6
Bit 7
Note : Before the A/D converter operation starts, the ADENA bit should
be set to 1.
Should be set to 0.
START. A/D Converter Start/Stop Control Bit.
0 = Stops A/D Converter
1 = Starts A/D Converter
