Bit Bit 
Name 
Initial 
Value R/W  Description 
MPIE 
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 ORER 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 12.5, 
Multiprocessor Communication Function. 
TEIE 
R/W 
Transmit End Interrupt Enable 
When this bit is set to 1, a TEI interrupt request is 
enabled. 
CKE1 
CKE0 
R/W 
R/W 
Clock Enable 1, 0 
These bits select the clock source and SCK pin 
function. 
Asynchronous mode 
00: Internal clock 
      (SCK pin functions as I/O port.) 
01: Internal clock 
      (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.) 
[Legend] 
X: Don't
