Table 9–43. DMA Request Mapping—MCSI2

This section provides information specific to MCSI2 (Figure 9–30) on the

OMAP5910 device.

Table 9–41 identifies the MCSI2 I/O pins.

I/O Direction

Table 9–42 identifies the MCSI2 interrupts. MCSI2 generates level 2 interrupts

for both the DSP and the MPU. Only one MPU MCSI2 interrupt covers TX, RX,

and frame error conditions; software must check the MCSI2 status register to

determine the interrupt source.

Incoming Interrupts

MCSI2 TX interrupt

MCSI2 RX interrupt

MCSI2 Frame Error

Table 9–43 identifies MCSI2 DMA request lines. Only the DSP DMA controller

can transfer MCSI2 data; there is no MPU DMA capability.
