NOTES:
1. When using standard serial I/O mode 1, to input "H" to the TxD pin is necessary while the RESET pin
is held "L". Therefore, connect this pin to V
system not to affect a data transfer after reset, because this pin changes to a data-output pin
2. Set the following, either or both.

-Connect the CE pin to V
