0xE008 0008)
This register contains the data to be transmitted or the data just received. The CPU can
read and write to this register only while it is not in the process of shifting a byte, when the
SI bit is set. Data in I2DAT remains stable as long as the SI bit is set. Data in I2DAT is
always shifted from right to left: the first bit to be transmitted is the MSB (bit 7), and after a
byte has been received, the first bit of received data is located at the MSB of I2DAT.

These registers are readable and writable, and is only used when an I
slave mode. In master mode, this register has no effect. The LSB of I2ADR is the general
call bit. When this bit is set, the general call address (0x00) is recognized.

Software must set values for the registers I2SCLH and I2SCLL to select the appropriate
data rate and duty cycle. I2SCLH defines the number of PCLK cycles for the SCL high
time, I2SCLL defines the number of PCLK cycles for the SCL low time. The frequency is
determined by the following formula (f
