48.2.3 LPUART Control Register (LPUARTx_CTRL)
This read/write register controls various optional features of the LPUART system. This
register should only be altered when the transmitter and receiver are both disabled.

R8T9
Receive Bit 8 / Transmit Bit 9
R8 is the ninth data bit received when the LPUART is configured for 9-bit or 10-bit data formats. When
reading 9-bit or 10-bit data, read R8 before reading LPUART_DATA.
T9 is the tenth data bit received when the LPUART is configured for 10-bit data formats. When writing 10-
bit data, write T9 before writing LPUART_DATA. If T9 does not need to change from its previous value,
such as when it is used to generate address mark or parity, they it need not be written each time
LPUART_DATA is written.

Receive Bit 9 / Transmit Bit 8
R9 is the tenth data bit received when the LPUART is configured for 10-bit data formats. When reading
10-bit data, read R9 before reading LPUART_DATA
T8 is the ninth data bit received when the LPUART is configured for 9-bit or 10-bit data formats. When
writing 9-bit or 10-bit data, write T8 before writing LPUART_DATA. If T8 does not need to change from its
previous value, such as when it is used to generate address mark or parity, they it need not be written
each time LPUART_DATA is written.
