I/O Processor Registers
Miscellaneous SRU Registers
(SRU_EXT_MISCx, Group E)
The Miscellaneous Signal Routing registers are a very powerful and versa-
tile feature of the DAI. These registers allow external pins, timers, and
clocks to serve as interrupt sources or timer inputs and outputs. They also
allow pins to connect to other pins, or to invert the logic of other pins.
