Receive Start Demand
A write to this register will trigger W89C841F receive DMA to
fetch the descriptor for progressing the receiving operation
when W89C841F receive DMA is staying at the suspend
state. Otherwise, the write operation will have no effect.
C0c/CRDLA Receive Descriptors List Addresses
The register defines the start address of the receive descriptor list. It should be updated only when the
receive DMA state machine is staying at the stop state.

Must be written as 0 for double word alignment.
C10/CTDLA Transmit Descriptors List Addresses
The register defines the start address of the transmit descriptor list. It should be updated only when the
transmission DMA state machine is staying at the stop state.

Must be written as 0 for double word alignment.
C14/CISR Interrupt Status Register
Most bits of this register report the interrupt status. The assertion of the interrupt status, reported by
bits 0 to bit 14 and the corresponding interrupt mask bits will cause a hardware interrupt to the host. A
write with 1 value the status bit will clear them and write 0 will have no effect.
