Table 9–1. McBSP1 Pin Descriptions

The operation of the OMAP5910 McBSPs is consistent with the SPRU317,
with the following exceptions and clarifications:
-
Only DXENA = 0 setting is supported.
-
The transmit output (DX) pins don not go to high impedance when the
transmitter in not actively sending data. In other words, the OMAP5910
always actively drives the DX pins.
-
The CLKS input is only available on McBSP1.
-
The receiver can only operate in slave mode on McBSP1 and McBSP3.
This section provides information specific to McBSP1 of the OMAP5910
device. For a full description of McBSP functionality and register descriptions,
see the TMS320C55x DSP Peripherals Reference Guide (literature number
SPRU317).
Table 9–1 identifies the McBSP1 I/O pins.
