Writing a one to this bit terminates the current transfer, sending a STOP condition after the shifter has become idle. If there are
additional pending transfers, they will have to be explicitly restarted by software after the STOP condition has been successfully
sent.
Writing a zero to this bit has no effect.
If the TWIM master interface is enabled, writing a one to this bit resets the TWIM. All transfers are halted immediately, possibly
violating the bus semantics.
If the TWIM master interface is not enabled, it must first be enabled before writing a one to this bit.
Writing a zero to this bit has no effect.
Writing a one to this bit disables SMBus mode.
Writing a zero to this bit has no effect.
Writing a one to this bit enables SMBus mode.
Writing a zero to this bit has no effect.
Writing a one to this bit disables the master interface.
Writing a zero to this bit has no effect.
Writing a one to this bit enables the master interface.
Writing a zero to this bit has no effect.
