Section 15 Serial Communication Interface (SCI)
For the relation between the clock source, the bit rate register setting, and the baud rate, see
section 15.2.9, Bit Rate Register (SCBRR1).
Bit 1: CKS1

1
Note: Pck: Peripheral clock
15.2.6
The SCSCR1 register performs enabling or disabling of SCI transfer operations, serial clock
output in asynchronous mode, and interrupt requests, and selection of the serial clock source.
SCSCR1 can be read or written to by the CPU at all times.
SCSCR1 is initialized to H'00 by a power-on reset or manual reset, in standby mode, and in the
module standby state.
Bit 7—Transmit Interrupt Enable (TIE): Enables or disables transmit-data-empty interrupt
(TXI) request generation when serial transmit data is transferred from SCTDR1 to SCTSR1 and
the TDRE flag in SCSSR1 is set to 1.
Bit 7: TIE

Serial Control Register (SCSCR1)
TXI interrupt requests can be cleared by reading 1 from the TDRE flag, then clearing it
to 0, or by clearing the TIE bit to 0.
