McBSP Falling Edge Transmit Timing in Slave Mode 6.6.1.2 McBSP in TDM—Multipoint Mode (McBSP3) For TDM application in multipoint mode, OMAP3530/25 is considered as a slave. Table 6-69 and Table 6- 70 assume testing over the operating conditions and electrical characteristic conditions described below. Table 6-68.
