Bits 1 and 0—Clock Select 1 and 0 (CKS1, CKS0): These bits select the clock source for the
baud rate generator. The clock source can be selected from , /4, /16, and /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 14.2.8, Bit Rate Register (BRR).
14.2.6
SCR is a register that performs enabling or disabling of SCI transfer operations, serial clock output
in asynchronous mode, and interrupt requests, and selection of the serial clock source.
SCR can be read or written to by the CPU at all times.
SCR is initialized to H'00 by a reset, and in standby mode or module stop mode.
Bit 7—Transmit Interrupt Enable (TIE): Enables or disables transmit data empty interrupt
(TXI) request generation when serial transmit data is transferred from TDR to TSR and the TDRE
flag in SSR is set to 1.
