Description
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 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 14.6,
Multiprocessor Communication Function.
Transmit End Interrupt Enable
When this bit is set to 1, the TEI interrupt request is
enabled.
Clock Enable 0 and 1
Selects the clock source.
Asynchronous mode:
00: Internal baud rate generator
01: Internal baud rate generator
10: External clock
11: Reserved
00: Internal clock (SCK3 pin functions as clock output)
01: Reserved
10: External clock (SCK3 pin functions as clock input)
11: Reserved
Outputs a clock of the same frequency as the bit rate
Inputs a clock with a frequency 16 times the bit rate
Clocked synchronous mode:
from the SCK3 pin.
from the SCK3 pin.
