This read/write bit enables the SCTE bit to generate ESCI transmitter interrupt requests. Setting the
SCTIE bit in SCC2 enables the SCTE bit to generate interrupt requests.
This read/write bit enables the TC bit to generate ESCI transmitter interrupt requests.
This read/write bit enables the SCRF bit to generate ESCI receiver interrupt requests. Setting the
SCRIE bit in SCC2 enables the SCRF bit to generate interrupt requests.
This read/write bit enables the IDLE bit to generate ESCI receiver interrupt requests.
Setting this read/write bit begins the transmission by sending a preamble of 10 or 11 1s from the
transmit shift register to the TxD pin. If software clears the TE bit, the transmitter completes any
transmission in progress before the TxD returns to the idle condition (high). Clearing and then setting
TE during a transmission queues an idle character to be sent after the character currently being
transmitted.
Setting this read/write bit enables the receiver. Clearing the RE bit disables the receiver but does not
affect receiver interrupt flag bits.

Writing to the TE bit is not allowed when the enable ESCI bit (ENSCI) is
clear. ENSCI is in ESCI control register 1.
