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