15.3.6 Serial Control Register (SCR)
SCR performs enabling or disabling of SCI transfer operations and interrupt requests, and
selection of the transfer/receive clock source. For details on interrupt requests, refer to section
15.9, Interrupts Sources. Some bit functions of SCR differ in normal serial communication
interface mode and Smart Card interface mode.
Normal Serial Communication Interface Mode (When SMIF in SCMR is 0)
Bit Bit Name Initial Value R/W Description
7 TIE 0 R/W Transmit Interrupt Enable
When this bit is set to 1, TXI interrupt request is
enabled.
6 RIE 0 R/W Receive Interrupt Enable
When this bit is set to 1, RXI and ERI interrupt
requests are enabled.
5TE 0 R/W
Transmit Enable
When this bit s set to 1, transmission is enabled.
4 RE 0 R/W Receive Enable:
When this bit is set to 1, reception is enabled.
3 MPIE 0 R/W Multiprocessor Interrupt Enable (enabled only
when the MP bit in SMR is 1 in asynchronous
mode)
When this bit is set to 1, receive data in which the
multiprocessor bit is 0 is skipped, and setting of
the RDRF, FER, and ORER status flags in SSR is
prohibited. On receiving data in which the
multiprocessor bit is 1, this bit is automatically
cleared and normal reception is resumed. For
details, refer to section 15.5, Multiprocessor
Communication Function.
2 TEIE 0 R/W Transmit End Interrupt Enable
When this bit is set to 1, TEI interrupt request is
enabled.
