UART2 Special Mode Register
The UART2 special mode register (address 037716) is used to control UART2 in various ways.
Figure 1.16.26 shows the UART2 special mode register.
Bit 0 of the UART2 special mode register (037716) is used as the I2C mode select bit.
Setting “1” in the I2C mode select bit (bit 0) goes the circuit to achieve the I2C bus (simplified I2C bus)
interface effective.
Table 1.16.9 shows the relation between the I2C mode select bit and respective control workings.
Since this function uses clock-synchronous serial I/O mode, set this bit to “0” in UART mode.

Note 1: Nothing but “0” may be written.
Note 2: When not in I2C mode, do not set this bit by writing a “1”. During normal mode, set it to “0”. When this
bit = “0”, UART2 special mode register 3 (U2SMR3 at address 037516) bits 7 to 5 (DL2 to DL0 = SDA
digital delay setup bits) are initialized to “000”, with the analog delay circuit selected. Also, when SDDS
= “0”, the U2SMR3 register cannot be read or written to.
Note 3: When analog delay is selected, only the analog delay value is effective; when digital delay is selected,
only the digital delay value is effective.

Nothing is assigned.
In an attempt to write to these bits, write “0”. The value, if read, turns out to be
indeterminate. However, when SDDS = “1”, the value “0” is read out (Note 1)

Note 1: This bit can be read or written to when UART2 special mode register (U2SMR at address 037716) bit
7 (SDDS: SDA digital delay select bit) = “1”. When the initial value of UART2 special mode register 3
(U2SMR3) is read after setting SDDS = “1”, the value is “0016”. When writing to UART2 special mode
register 3 (U2SMR3) after setting SDDS = “1”, be sure to write 0's to bits 0–4. When SDDS = “0”,
this register cannot be written to; when read, the value is indeterminate.
Note 2: These bits are initialized to “000” when SDDS = “0”, with the analog delay circuit selected. After a reset,
these bits are set to “000”, with the analog delay circuit selected. However, because these bits can be
read only when SDDS = “1”, the value read from these bits when SDDS = “0” is indeterminate.
Note 3: When analog delay is selected, only the analog delay value is effective; when digital delay is selected,
only the digital delay value is effective.
Note 4: The amount of delay varies with the load on SCL and SDA pins. Also, when using an external clock, the
amount of delay increases by about 100 ns, so be sure to take this into account when using the device.
