B-Channel Routes and Access to B-Channel Data
2.3.6
µP Access to B Channels
The B1 and/or B2 channels are accessed by reading the B1CR/B2CR or by reading and writing
the C1R/C2R registers. The µP access can be synchronized to the serial interface by means
of a Synchronous Transfer programmed in the STCR register.
The read/write access possibilities are shown in table 3.
