11.2.4 Serial Communication Unit n Transmission Interval Setting Register (SUnDLY)
SUnDLY is a specific function register (SFR) to set the transmission frame interval of serial communication. It is used
for the slave device to wait for a data reception process when continuously transmitting the serial data.
Address:
0xF604(SU0DLYL), 0xF624(SU1DLYL), 0xF644(SU2DLYL),
0xF664(SU3DLYL), 0xF684(SU4DLYL), 0xF6A4(SU5DLYL)

Description
7 to 0
SUnDLY7 to
SUnDLY0
These bits are used to set the transmission frame interval in the SSIO mode or UART mode.
When SUnDLY is 0x00, the transmission frame interval is “0”.
When SUnDLY is not 0x00, the transmission frame interval of serial communication is calculated by the following
formula.
In the SSIO mode:
Transmit frame interval =
Transfer clock cycle*
1
x ROUNDUP*
2
( (Setting value in SUnDLYL re 2) / dividing ratio of HSCLK )
In the UART mode:
Transmit frame interval =
Base clock cycle*
3
x (1) x ROUNDUP*
2
( (Setting value in SUnDLYL re 2) / (1) )
*
1
: The transfer clock cycle = (dividing ratio of HSCLK chosen in SnCK4 to 0 bits) x (HSCLK cycle)
*
2
: ROUNDUP = Round the answer up to the nearest whole number
*
3
: The base clock is chosen by setting the SIOnMOD register in the SSIO mode and by setting the UAnMOD register in
the UART mode.
