Bits 1 and 0—Clock Select 1 and 0 (CKS1, CKS0): These bits select the clock source for the on-
chip baud rate generator. The clock source can be selected from Pck, Pck/4, Pck/16, and Pck/64,
according to the setting of bits CKS1 and CKS0.
For the relation between the clock source, the bit rate register setting, and the baud rate, see
section 16.2.8, Bit Rate Register (SCBRR2).

Note: Pck: Peripheral clock
16.2.6
The SCSCR2 register performs enabling or disabling of SCIF transfer operations, serial clock
output, and interrupt requests, and selection of the serial clock source.
SCSCR2 can be read or written to by the CPU at all times.
SCSCR2 is initialized to H'0000 by a power-on reset or manual reset. It is not initialized in
standby mode or in the module standby state.
Bits 15 to 8, and 2—Reserved: These bits are always read as 0, and should only be written with
0.
