If user wants to terminate this communication,
he can set MODE = 1 to send out STOP condition
or clear RSTART = 0 to send out REPEAT START
System will wait if user didn't send out the first byte
data. As user loaded one byte data into TXDAT buffer,
system will latch to shift register and send out MSB bit
right away.
After sending out first byte data, user will get another
INTTX to put next byte data into TXDAT buffer,
If user does not send out the second byte data, the
system will wait again after shifted out first byte data.
