DUA0 (bit 2)
The DUA0 bit is used to control UART operation.
DUA0 Description
0 Enable operating UART (initial value)
1 Disable operating UART
Note:
•When any flag is set to "1" (disable operation), the function of the applicable block is reset (all registers are
initialized) and the clock supply to such block stops. When this flag is set to "1", the writing to all registers in the
applicable block becomes invalid, and thus the reading from such register becomes the initial value. When using the
function of the applicable block, ensure to reset the applicable flag of this block control register to "0" (enable
operation).
•See Chapter 11, “UART” for detail about operation of UART.
