Store transmit data
When detecting that the ICDRS register is empty, the stored transmit data is transferred to the
ICDRS register and the starts transmit data.
When the next transmit data is w ritten to the ICDRT register during transmitting the data of the
ICDRS register, continuous transmit is enabled. When the MLS bit in the ICMR register is set to
1 (data transferred by LSB-first) and after the data is w ritten to the ICDRT register, the MSB
and LSB inverted data is read.
