Figure 7–45. Communication Processor Data Interface

Figure 7–45 illustrates the use of McBSP2 as a communication processor

data interface that is the master of TX and slave for RX communications. The

actual implementation is generic: FSX, CLKX, FSR, and CLKR are bidirection-

al. The direction of these signals is configured by registers in the McBSP

module. The CLKS signal is the active input clock for the McBSP modem

block. The active input clock can be changed in a McBSP register, but register

activity on CLKS is required to perform the set up and write to the McBSP.
