(initializing value is "0016" at SDDS = "1")
Nothing is assigned.
In an attempt to write to this bit, write “0”. The value, if read, turns out to be “0”.
“0” is read out when SDDS = 1.

Notes 1: Reading and writing is possible when bit7 (SDDS = SDA digital delay selection
bit) of UART2 special mode register (U2SMR/address 037716) is "1". When
set SDDS = "1" and read out initialized value of UART2 special mode register
3(U2SMR3), this value is "0016".When set SDDS = "1" and write to UART2
special mode register 3(U2SMR3), set "0" to bit 0 to bit 4. When SDDS = "0",
writing is enable. When read out, this value is indeterminate.
2: When SDDS = "0" , this bit is initialized and become "000", selected analog
delay circuit. This bit is become "000" after end reset released, and selected
analog delay circuit. Reading out is possible when only SDDS = "1". when
SDDS = "0", value which was read out is indeterminate.
3: Delaying ; Only analog delay value when analog delay is selected, and only
digital delay value when digital delay is selected.
4: Delay level depends on SCL pin and SDA pin. And, when use external clock,
delay is increase around 100ns. So test first, and use this.
0 0 0 : Analog delay
0 0 1 : 2 cycle of 1/f (Xin)(Digital delay)
0 1 0 : 3 cycle of 1/f (Xin)(Digital delay)
0 1 1 : 4 cycle of 1/f (Xin)(Digital delay)
1 0 0 : 5 cycle of 1/f (Xin)(Digital delay)
1 0 1 : 6 cycle of 1/f (Xin)(Digital delay)
1 1 0 : 7 cycle of 1/f (Xin)(Digital delay)
1 1 1 : 8 cycle of 1/f (Xin)(Digital delay)
