13:8 : DBC[6:1] - denounce filter threshold for baud rate measurement (MMODE=0)
DBC[0] is always set to logic 1.
DBC[6:0] form the upper threshold value for the denouncing filter.
Denounce filter is reset to 81 which results in minimum filter delay of
81x62,5ns=5,1us@16MHz
3 : AUTO_BAUD
automatically copy baud measurement result to baud config register after a valid baud
measurement (expecting SYNC Byte)
--> AUTO_BAUD_TRIGGERED will be set
NOTE: During baud measurement the receiver is disabled an therefore no data will be re-
ceived, only the measurement logic is active which will generate a
measurement finish flag (configurable as interrupt)
2 : AUTO_MEAS
automatically start a baud rate measurement after reception of a valid break
--> AUTO_MEAS_TRIGGERED will be set
NOTE: AUTO_MEAS mode suppresses the flag specific flag generation (see sci_status -> BRF)
1 : MMODE measurement mode select
0 -> baud rate measurement, counter runs with system clock and measures time between 4
falling edges (8 bit length are measured), bouncer is enabled
Note: baud measurement expects a 0x55 data byte to measure, this is the SYNC byte in the
LIN protocol
1 -> break time measurement, counter runs with 16 x baud rate, measures time when RxD
line is zero
NOTE: only applicable together with MEN control bit
0 : MEN - measurement enable
Set to '1' to start a measurement
When measurement is finished, MEN bit will be cleared automatically
NOTE: When AUTO_MEAS bit is set MEN must not be used
NOTE: Writing a '0' to MEN resets the measurement logic and allows a clean restart
reset value: 0x2800
15:0 : MEASUREMENT COUNTER
Counter is cleared by every start of a new measurement
When the measurement counter overflows the counter value is saturated to 0xFFFF and the
measurement will be stopped (MF flag set). The measurement should be
repeated with an adapted baud rate setting.
Note: In Baud measurement mode the result of the baud measurement (8 bit length) is di-
vided by 4 and rounded (resulting 2 bit length value) the resulting 16 bit
can be fed into the baud divider register to adjust the baud rate.
