Divider X Enable
The BRD = Baud Rate Divider, and the baud rate equation is
Baud Rate = Clock / [M * (BRD + 2)]; The default value of M is 16.
1 = Enable divider X (the equation of M = X+1, but DIVIDER_X [27:24] must >= 8).
0 = Disable divider X (the equation of M = 16)
Refer to the table below for more information.
Note: When in IrDA mode, this bit must disable.
Divider X equal 1
1 = Divider M = 1 (the equation of M = 1, but BRD [15:0] must >= 3).
0 = Divider M = X (the equation of M = X+1, but DIVIDER_X[27:24] must >= 8)
Refer to the Table 5-12 below for more information.
Divider X
The baud rate divider M = X+1.
