MLI, V2.0
Combined with the baud rate as derived in the MLI module (see Equation (23.1) on
Page 23-65) and the MLIx_FDR fractional divider setup, the resulting MLI baud rate is
defined by:
(23.4)
(23.5)
Equation (23.4) applies to normal divider mode of the fractional divider
(FDR.DM = 01
B
). Equation (23.5) applies to fractional divider mode (FDR.DM = 10
B
).
After a reset operation, both MLI modules are enabled in normal divider mode. According
the MLIx_FDR register’s reset value of 03FF 43FF
H
, the selected baud rate is f
DMA
/2.
Note that the DMA controller is also enabled after a reset operation with clock f
DMA
= f
SYS
.
The receiver baud rate is defined by the following formula.
