START: Start the A/D conversion
0→1→0: Start
This bit is used to initiate an A/D conversion process. The bit is normally low but if set
high and then cleared low again, the A/D converter will initiate a conversion process.
When the bit is set high the A/D converter will be reset.
ADBZ: A/D converter busy flag
0: No A/D conversion is in progress
1: A/D conversion is in progress
This read only flag is used to indicate whether the A/D conversion is in progress or
not. When the START bit is set from low to high and then to low again, the ADBZ flag
will be set to 1 to indicate that the A/D conversion is initiated. The ADBZ flag will be
cleared to 0 after the A/D conversion is complete.
ADCEN: A/D converter function enable control
0: Disable
1: Enable
This bit controls the A/D internal function. This bit should be set to one to enable
the A/D converter. If the bit is set low, then the A/D converter will be switched off
reducing the device power consumption. When the A/D converter function is disabled,
the contents of the A/D data register pair known as SADOH and SADOL will be
unchanged.
ADRFS: A/D converter data format select
0: A/D converter data format → SADOH=D[11:4]; SADOL=D[3:0]
1: A/D converter data format → SADOH=D[11:8]; SADOL=D[7:0]
This bit controls the format of the 12-bit converted A/D value in the two A/D data
registers. Details are provided in the A/D data register section.
