Multiprocessor Interrupt Enable (enabled only when the
Transmit End Interrupt Enable
Description
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, see
section 13.5, Multiprocessor Communication Function.
This bit is set to 1, TEI interrupt request is enabled.
Clock Enable 0 and 1
Selects the clock source and SCK pin function.
Asynchronous mode
00: Internal baud rate generator
01: Internal baud rate generator
1X: External clock
Clocked synchronous mode
0X: Internal clock (SCK pin functions as clock output)
1X: External clock (SCK pin functions as clock input)
SCK pin functions as I/O port
Outputs a clock of the same frequency as the bit
rate from the SCK pin.
Inputs a clock with a frequency 16 times the bit rate
from the SCK pin.
