C8051F52x/F52xA/F53x/F53xA
20.5.2. Synch Break and Synch Field Length Check
On C8051F52x/F53x devices, the check of sync field length versus sync break length is incorrect. On
C8051F52xA/F53xA devices, the sync break length must be larger than 10 bit times (of the measured bit
time) to enable the synchronization.
