McBSP3 Application Example: Optical Interface

Table 9–13 identifies the McBSP3 interrupts. McBSP3 generates level 2

interrupts for both the DSP and the MPU.

Incoming Interrupts

McBSP3 TX interrupt

McBSP3 RX interrupt

Table 9–14 identifies McBSP3 DMA request lines.

DMA Request Source

With the assistance of two GPIOs, McBSP3 is configured to connect to an

external optical audio interface (see Figure 9–6) device such as the Sanyo

LC89051V. 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 activity

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

Section 9.4.4.1 through Section 9.4.4.12 explain the McBSP register setup for

optical interface with 8-bit transfer per frame in SPI master mode and GPIO
