___________
Note 1: When using standard serial input/output mode 1, the TxD pin must be held high while the RESET
pin is pulled low. Therefore, connect this pin to VCC1 via a resistor. Because this pin is directed for
data output after reset, adjust the pull-up resistance value in the system so that data transfers will
not be affected.
