DIV_X_EN
Divider X Enable Control
0 = Divider X Disabled (the equation of M = 16).
1 = Divider X Enabled (the equation of M = X+1, but DIVIDER_X(UA_BAUD[27:24]) must
>= 8).
Refer to the table below for more information.
Note:
In IrDA mode, this bit must disable.
Note:
The BRD = Baud Rate Divider, and the baud rate equation is
Baud Rate = Clock / [M * (BRD + 2)]; The default value of M is 16.
[28]
DIV_X_ONE
Divider X Equal to 1
0 = Divider M = X (the equation of M = X+1, but DIVIDER_X(UA_BAUD[27:24]) must >=
8).
1 = Divider M = 1 (the equation of M = 1, but BRD(UA_BAUD[15:0]) must >= 3).

DIVIDER_X
Divider X
