ST20-GP1
ASCTxBuffer register
Writing to the transmit buffer register starts data transmission.
ASCRxBuffer register
The received data and, if provided by the selected operating mode, the received parity bit can be
read from the receive buffer register.

Transmit buffer data D2
Transmit buffer data D3
Transmit buffer data D4
Transmit buffer data D5
Transmit buffer data D6
Transmit buffer data D7, or parity bit - dependent on the operating mode (the setting of the
Mode field in the ASCControl register).
Transmit buffer data D8, or parity bit, or wake-up bit or undefined - dependent on the operating
mode (the setting of the Mode field in the ASCControl register).
Note: If the Mode field selects an 8-bit frame then this bit should be written as 0.
