Function

Transmit buffer data D0

Transmit buffer data D1

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.

RESERVED. Write 0.

Table 13.3 ASCTxBuffer register format

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.
