Bit Bit Name
7 TIE
6 RIE
Initial
Value R/W Description
0 R/W Clock Enable 1, 0
0 R/W These bits select the clock source and SCK pin
function.
•
00: On-chip baud rate generator
01: On-chip baud rate generator
1X: External clock
•
0X: Internal clock
1X: External clock
Initial
Value R/W Description
0 R/W Transmit Interrupt Enable
When this bit is set to 1,a TXI interrupt request is
enabled.
A TXI interrupt request can be cancelled by reading 1
from the TDRE flag and then clearing the flag to 0, or by
clearing the TIE bit to 0.
0 R/W Receive Interrupt Enable
When this bit is set to 1, RXI and ERI interrupt requests
are enabled.
RXI and ERI interrupt requests can be cancelled by
reading 1 from the RDRF, FER, PER, or ORER flag and
then clearing the flag to 0, or by clearing the RIE bit to
0.
Section 13 Serial Communication Interface (SCI)
Asynchronous mode
(SCK pin functions as I/O port.)
(Outputs a clock with 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.)
Clocked synchronous mode
(SCK pin functions as clock output.)
(SCK pin functions as clock input.)
