(1) ADnCSPD (A-Dn conversion rate selection) bit
This bit selects an A-D conversion rate for the A-Dn converter during scan mode. Setting this bit
to 0 selects a normal speed, and setting this bit to 1 selects a x2 speed (two times normal speed).
(2) ANnSCAN (A-Dn scan loop selection) bits (D12-D15)
The ANnSCAN (A-Dn scan loop selection) bits set the channels to be scanned during scan mode
of the A-Dn converter. In this case, writes to D14 and D15 have no effect.
The ANnSCAN (A-Dn scan loop selection) bits when read during scan operation show the status
of the A-Dn converter, indicating the channel it is converting.
The value read from these bits during single mode are always "B'0000." If A-D conversion is
halted by setting Scan Mode Register 0 ADnCSTP (A-Dn conversion stop) bit to 1 during scan
mode execution, the bits when read at this time show the value of the channel in which the A-D
conversion has been canceled. Also, if halted during single mode conversion in special operation
mode "Forcible single mode execution during scan mode," the bits when read at this time show
the value of the channel in which the A-D conversion has been canceled in the middle of scan.
