Section 15 Serial Communication Interface with FIFO (SCIF)
15.3.13 Serial Extension Mode Register (SCEMR)
The CPU can always read from or write to SCEMR. Setting the BGDM bit in this register to 1
allows the baud rate generator in the SCIF operates in double-speed mode when asynchronous
mode is selected (by setting the C/A bit in SCSMR to 0) and an internal clock is selected as a
clock source and the SCK pin is set as an input pin (by setting the CKE[1:0] bits in SCSCR to 00).

Description
Reserved
These bits are always read as 0. The write value
should always be 0.
Baud Rate Generator Double-Speed Mode
When the BGDM bit is set to 1, the baud rate
generator in the SCIF operates in double-speed
mode. This bit is valid only when asynchronous mode
is selected by setting the C/
an internal clock is selected as a clock source and the
SCK pin is set as an input pin by setting the CKE[1:0]
bits in SCSCR to 00. In other settings, this bit is
invalid (the baud rate generator operates in normal
mode regardless of the BGDM setting).
0: Normal mode
1: Double-speed mode
Reserved
These bits are always read as 0. The write value
should always be 0.
Base Clock Select in Asynchronous Mode
This bit selects the base clock frequency within a bit
period in asynchronous mode. This bit is valid only in
asynchronous mode (when the C/
0).
0: Base clock frequency is 16 times the bit rate
1: Base clock frequency is 8 times the bit rate
