Field Description
14
RXEDGIE
RX Input Active Edge Interrupt Enable
Enables the receive input active edge, RXEDGIF, to generate interrupt requests. Changing CTRL[LOOP]
or CTRL[RSRC] when RXEDGIE is set can cause the RXEDGIF to set.
0 Hardware interrupts from LPUART_STAT[RXEDGIF] disabled (use polling).
1 Hardware interrupt requested when LPUART_STAT[RXEDGIF] flag is 1.
13
SBNS
Stop Bit Number Select
SBNS determines whether data characters are one or two stop bits. This bit should only be changed when
the transmitter and receiver are both disabled.
0 One stop bit.
1 Two stop bits.
SBR Baud Rate Modulo Divisor.
The 13 bits in SBR[12:0] set the modulo divide rate for the baud rate generator. When SBR is 1 - 8191,
the baud rate equals "baud clock / ((OSR+1) × SBR)". The 13-bit baud rate setting [SBR12:SBR0] must
only be updated when the transmitter and receiver are both disabled (LPUART_CTRL[RE] and
LPUART_CTRL[TE] are both 0).
