What is the value of TxD pin when TE bit of SCR is set to 1?

Latest Updated:03/26/2009

Question:

What is the initial value of TxD pin, when the TE bit of serial control register (SCR) is set to 1?

Answer:

When TE bit is set to 1, the initial value of TxD pin automatically takes on a high level in the asynchronous and clock synchronous modes. However, it is necessary to set to 1 the TXD bit of the port mode register before TE bit is set, when setting the TxD pin to output.
