Bit
Bit Name Value R/W Description
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 OER 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 16.6, Multiprocessor
Communication Function.
2
TEIE
0
R/W Transmit End Interrupt Enable
When this bit is set to 1, TEI interrupt request is enabled.

R/W Selects the clock source.
• Asynchronous mode
00: On-chip baud rate generator
01: On-chip baud rate generator
Outputs a clock of the same frequency as the bit rate
from the SCK3 pin.
10: External clock
Inputs a clock with a frequency 16 times the bit rate
from the SCK3 pin.
11: Reserved
• Clocked synchronous mode
00: On-chip clock (SCK3 pin functions as clock output)
01: Reserved
10: External clock (SCK3 pin functions as clock input)
11: Reserved
