 * Prescales the I2C module clock for bit rate selection. This field and the

 * time, and the SCL stop hold time. For a list of values corresponding to each ICR

 * clock speed (Hz)/(mul * SCL divider) The SDA hold time is the delay from the
 * falling edge of SCL (I2C clock) to the changing of SDA (I2C data). SDA hold time =
 * I2C module clock period (s) * mul * SDA hold value The SCL start hold time is
 * the delay from the falling edge of SDA (I2C data) while SCL is high (start

 * In master transmit mode, when data is written to this register, a data

 * mode, reading this register initiates receiving of the next byte of data. When
 * making the transition out of master receive mode, switch the I2C mode before
 * reading the Data register to prevent an inadvertent initiation of a master
 * receive data transfer. In slave mode, the same functions are available after an
 * address match occurs. The C1[TX] bit must correctly reflect the desired direction
 * of transfer in master and slave modes for the transmission to begin. For
 * example, if the I2C module is configured for master transmit but a master receive
 * is desired, reading the Data register does not initiate the receive. Reading
 * the Data register returns the last byte received while the I2C module is
 * configured in master receive or slave receive mode. The Data register does not
 * reflect every byte that is transmitted on the I2C bus, and neither can software
 * verify that a byte has been written to the Data register correctly by reading it
 * back. In master transmit mode, the first byte of data written to the Data
 * register following assertion of MST (start bit) or assertion of RSTA (repeated
 * start bit) is used for the address transfer and must consist of the calling

 * to 1. A transfer begins. The MCU signals the I2C module to enter stop mode. The
 * byte currently being transferred, including both address and data, completes
 * its transfer. The I2C slave or master acknowledges that the in-transfer byte
 * completed its transfer and acknowledges the request to enter stop mode. After
 * receiving the I2C module's acknowledgment of the request to enter stop mode,
 * the MCU determines whether to shut off the I2C module's clock. If the SHEN bit
 * is set to 1 and the I2C module is in an idle or disabled state when the MCU
 * signals to enter stop mode, the module immediately acknowledges the request to
 * enter stop mode. If SHEN is cleared to 0 and the overall data transmission or
 * reception that was suspended by stop mode entry was incomplete: To resume the
 * overall transmission or reception after the MCU exits stop mode, software must
 * reinitialize the transfer by resending the address of the slave. If the I2C
 * Control Register 1's IICIE bit was set to 1 before the MCU entered stop mode,
 * system software will receive the interrupt triggered by the I2C Status Register's
 * TCF bit after the MCU wakes from the stop mode.

 * - 0 - Stop holdoff is disabled. The MCU's entry to stop mode is not gated.

 * @brief HW_I2C_SMB - I2C SMBus Control and Status register (RW)
 *
 * Reset value: 0x00U
 *
 * When the SCL and SDA signals are held high for a length of time greater than
 * the high timeout period, the SHTF1 flag sets. Before reaching this threshold,
 * while the system is detecting how long these signals are being held high, a
 * master assumes that the bus is free. However, the SHTF1 bit is set to 1 in the
 * bus transmission process with the idle bus state. When the TCKSEL bit is set,
 * there is no need to monitor the SHTF1 bit because the bus speed is too high to
 * match the protocol of SMBus.
