SCI Initialization (Asynchronous Mode) 

Before transmitting and receiving data, first clear the TE and RE bits in SCR to 0, then initialize 
the SCI as shown in figure 16.5. When the operating mode, transfer format, etc., is changed, the 
TE and RE bits must be cleared to 0 before making the change using the following procedure. 
When the TE bit is cleared to 0, the TDRE flag in SSR is set to 1. Note that clearing the RE bit to 
0 does not initialize the contents of the RDRF, PER, FER, and ORER flags in SSR, or the contents 
of RDR. When the external clock is used in asynchronous mode, the clock must be supplied even 
during initialization. 

Wait

<Initialization completion>

Start initialization

Set data transfer format in

SMR and SCMR

[1]

Set CKE1 and CKE0 bits in SCR

(TE and RE bits are 0)

No

Yes

Set value in BRR

Clear TE and RE bits in SCR to 0

[2]

[3]

Set TE and RE bits in

SCR to 1, and set RIE, TIE, TEIE,

and MPIE bits

[4]

1-bit interval elapsed?

[1] Set the clock selection in SCR.   

Be sure to clear bits RIE, TIE, 
TEIE, and MPIE, and bits TE and 
RE, to 0.

When the clock is selected in 
asynchronous mode, it is output 
immediately after SCR settings are 
made.

[2] Set the data transfer format in SMR 

and SCMR.

[3] Write a value corresponding to the 

bit rate to BRR.  Not necessary if 
an external clock is used.

[4] Wait at least one bit interval, then 

set the TE bit or RE bit in SCR to 1.  
Also set the RIE, TIE, TEIE, and 
MPIE bits.

Setting the TE and RE bits enables 
the TxD and RxD pins to be used.
