+===============================
+Two Wire Interface in AVR DA/DB
+===============================
+
+Two Wire Interface is AVR peripheral capable of supporting both I\ :sup:`2`\ C
and SMBus.
+
+Usage
+=====
+
+
+Pointer to initialized ``struct i2c_master_s`` can be obtained using
+
+.. code-block:: c
+
+ FAR struct i2c_master_s *i2c;
+ i2c = avrdx_initialize_twi(0);
+
+
+This function will initialize the peripheral based on configuration specified
+via Kconfig. It may be called multiple times, only first call will perform
+the initialization - subsequent calls will only return the pointer.
+
+Deinitialization is currently not supported.
+
+The parameter denotes which peripheral is to be initialized. With current
chips,
+permitted values are ``0`` and ``1``.
+It is ignored if the chip has only single TWI interface.
+
+Configuration options
+=====================
+
+Pin selection
+-------------
+
+This option makes it possible to choose which I/O pins will be connected
+to the peripheral.
+
+Mode selection
+--------------
+
+The peripheral supports Standard, Fast and Fast Plus modes.
+
+Quick commands
+--------------
+
+SMBus permits transactions that contain no data. Instead, the R/nW bit
+is interpreted as a single-bit datum by the target device. If this is enabled,
+I\ :sup:`2`\ C messages with zero length are interpreted as quick commands. If
not,
+zero-length messages are not permitted and the transmission is rejected
+with ``EINVAL``
+
+Forbid NOSTART
+--------------
+
+NuttX upper half of the I\ :sup:`2`\ C driver permits ``I2C_M_NOSTART``
+flag for a message, indicating that the message is not a standalone entity
+but rather a continuation of previous message. Since not all drivers need
+this and program memory space is not unlimited on the chip, this configuration
+option can be used to remove support for such messages.
+
+Transmission that submits message with this flag will be rejected
+with ``EINVAL`` if this configuration option is set. Enable this only
+if you know internals of I\ :sup:`2`\ C drivers used by your application.
+
+Limitations
+===========
+
+Mode and addressing
+-------------------
+
+Currently, only master mode is supported.
+
+Only 7-bit addressing is supported. The peripheral does not support 10-bit
+addressing directly and the driver software does currently have no support
+for that either. I\ :sup:`2`\ C messages requesting 10-bit address
+are rejected with ``ENOTSUP``.
+
+Message limitations
+-------------------
+
+Maximum message count for single transmission is 127.
+
+The driver does not support ``I2C_M_NOSTOP`` flag for last submitted message.
+As per rules specified in ``include/nuttx/i2c/i2c_master.h``, the I\ :sup:`2`\
C
+driver lower half is supposed to leave the bus occupied if the last
+of the submitted messages has this ``NOSTOP`` flag set. This driver
+is not capable of doing that.
+
+Also not supported is ``I2C_M_NOSTART`` flag for first submitted message.
+First message within the transfer always starts with ``START`` condition.
+
+Messages with zero length (which are only permitted based on configuration
+- see above) may not specify ``I2C_M_NOSTART`` nor ``I2C_M_NOSTOP``.
+(Such a message is interpreted as a quick command and quick commands
+must end with a ``STOP`` condition according to the chip's documentation.)
+
+Inactivity timeout
+------------------
+
+The driver configures timeout for bus inactivity during initialization.
+This timeout is used by the hardware to switch its internal state
+from "bus is busy" or "bus is in unknown state" to "bus is idle."
+This transition otherwise only happens after a ``STOP`` condition is detected
+or when forced by software.
+
+This timeout remains in effect during normal TWI operation as well.
+Such a timeout is defined for SMBus but not for I\ :sup:`2`\ C; nevertheless,
+the driver does not distinguish between the two and the timeout is always
+in place.

+
+Note: When normal mode COUNT is 0, it will switch to the next PM state where
COUNT is not 0.
+
+Note: During light sleep, overall current consumption of board should drop
from 26ma (without any system load) to 3.5 mA on ESP32-S2 Saola-1.
+During deep sleep, current consumption of board should drop from 26 (without
any system load) to 1.24 mA.
