10-bit Mode select
The M10 bit causes a tenth, non-memory mapped bit to be part of the serial transmission. This tenth bit is
generated and interpreted as a parity bit. The M10 bit does not affect the LIN send or detect break
behavior. If M10 is set then both C1[M] and C1[PE] bits must also be set. This bit must be cleared when
C7816[ISO7816E] is set/enabled. Refer to

Baud Rate Fine Adjust
This bit field is used to add more timing resolution to the average baud frequency, in increments of 1/32.

All data received is transferred to the data buffer if MAEN2 is cleared.
All data received with the most significant bit cleared, is discarded. All data received with the most
significant bit set, is compared with contents of MA1 register. If no match occurs, the data is
discarded. If match occurs, data is transferred to the data buffer.This bit must be cleared when
C7816[ISO7816E] is set/enabled.
