Bits 1 and 0: Clock select 1 and 0 (CKS1, CKS0)
Bits 1 and 0 choose ø/64, ø/16, ø/2, or ø as the clock source for the baud rate generator.
For the relation between the clock source, bit rate register setting, and baud rate, see 8, Bit rate
register (BRR).

6. Serial control register 3 (SCR3)
SCR3 is an 8-bit register for selecting transmit or receive operation, the asynchronous mode clock
output, interrupt request enabling or disabling, and the transmit/receive clock source.
SCR3 can be read or written by the CPU at any time.
SCR3 is initialized to H'00 upon reset, and in standby, watch or module standby mode.
