ADSP-SC58x PKTE Register Descriptions
Interrupt Mask Disable Register
The host can use the
PKTE_IMSK_DIS
host interrupt. This register is a bitmap for each of the possible interrupt sources: A 1 clears the interrupt enable bit,
a 0 does not affect the interrupt enable bit in the
register avoids the time-consuming read-modify-write operation on the host.

Interface Error.
Write the PKTE_IMSK_DIS.IFERR bit to clear when the host requests a non 32-
bit access to the packet engine or when the packet engine receives an error writing data
back out to the host memory system.
PKTE Processing Error.
Write the PKTE_IMSK_DIS.PROCERR bit to clear an extended error that occurred
before, during or after processing the current packet in the packet engine.
PKTE Ring Error.
Write the PKTE_IMSK_DIS.RINGERR bit to clear a CDR overflow or an RDR
underflow.
Halt.
Write the PKTE_IMSK_DIS.HLT bit to clear when the packet engine is in the halt
state.
