PROCESSOR MODULE
16.5.2.3 SDMA MASK REGISTER. The 8-bit read/write SDMA mask register (SDMR) has
the same bit format as the SDMA status register. If a bit in the SDMA mask register is a 1,
the corresponding interrupt in the event register is enabled. If the bit is zero, the
corresponding interrupt is masked.
SBER—SDMA Channel Bus Error Mask (SDMA function)
0 = Disable the SDMA channel bus error interrupt.
1 = Enable the SDMA channel bus error interrupt.
Bits 1–5—Reserved
These bits are reserved and must be set to 0.
DSP2—DSP Chain 2 Transmitter Interrupt Mask (DSP function)
0 = Disable the DSP chain 2 transmitter interrupt, as described in
Section 16.3.3.3 DSP Event Register.
1 = Enable the DSP chain 2 transmitter interrupt.
DSP1—DSP Chain 1 Receiver Interrupt Mask (DSP function)
0 = Disable the DSP chain 1 receiver interrupt, as described in Section 16.3.3.3 DSP
Event Register.
1 = Enable the DSP chain 1 receiver interrupt.
