Interrupt Register - Spectrum Digital TMS320VC5509A EVM PLUS Technical Reference

Spectrum Digital, Inc
McBSP0SEL and McBSP2SEL control the McBSP0 and McBSP2. Since McBSP0 is
used for Serial Boot loading the McBSP.dr pin is routed to the serial ROM at power up.
When McBSP0 is used for AIC23B operation this bit must be set to a "1". McBSP2 is
used for MMC operation at power up. Setting this bit to a "1" the McBSP2 is routed to
the daughter card connector. The power-on state of these bits (both 0s) represents that
situation. Setting the corresponding bit for McBSP2 to "1" enables the McBSP to the
expansion daughter-card instead interface.

2.1.7 Interrupt Register

The EVM allows interrupts to be generated from the "Wake Up" switch, S4. These
interrupts can be routed to various pins on the VC5509A DSP. The interrupt register
does this routing. When the corresponding bit is set to a "1" the DSP will be interrupted
by the "Wake Up" switch. The interrupts to choose from are DSP interrupts 0, 1, or 3 as
shown in the table below.
