Description
Transmit Interrupt Enable
When this bit is set to 1, a TXI interrupt request is
enabled.
Receive Interrupt Enable
When this bit is set to 1, RXI and ERI interrupt
requests are enabled.
Transmit Enable
When this bit is set to 1, transmission is enabled.
Receive Enable
When this bit is set to 1, reception is enabled.
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
disabled. 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.
Transmit End Interrupt Enable
When this bit is set to 1, a TEI interrupt request is
enabled.
