Description
Transmit Interrupt Enable
When this bit is set to 1, 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 s 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
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.
Transmit End Interrupt Enable
When this bit is set to 1, TEI interrupt request is
enabled.
Clock Enable 1 and 0
Selects the clock source and SCK pin function.
Asynchronous mode
00: On-chip baud rate generator
SCK pin functions as I/O port
01: On-chip baud rate generator
(Outputs a clock of the same frequency as the bit
rate from the SCK pin.)
1X: External clock
(Inputs a clock with a frequency 16 times the bit
rate from the SCK pin.)
Clocked synchronous mode
0X: Internal clock (SCK pin functions as clock
output)
1X: External clock (SCK pin functions as clock
input)
