When generating start, stop, and restart conditions, set the STSPSEL bit in the U2SMR4 register to 0 and wait
for more than half cycle of the transfer clock before changing each condition generation bit (STAREQ,
RSTAREQ, and STPREQ) from 0 to 1.
Immediately after writing 00h to the U2BRG register, there may be a delay of up to 256 cycles of the count
source when the following data transmission/reception starts (including the timing when the TI bit in the U2C1
register is set to 0 (data present in the U2TB register)) and when the start bit is detected during reception).
