Switching between the external terminal
and internal register settings(for the
operation mode)
Valid only in MODE [3:0] set as follows :
(0101/0110/0111/1101/1110)
Corresponds to the external MODE
[3:0] pin.
Logic & DAC Sleep mode cannot be set.
The sleep mode by the register is valid
for only DAC through MR0[5].
